It's going to be a "budget DH bike" alright, but I wouldn't call it "really nice".
My buddy is a bike shop owner, who sells Marin amongst other brands. He says that Marin has by far the worst production quality he's ever seen on any "legit" bike brand. Misaligned or warped frames, terrible welds and badly machined bearing seats are apparently common with them. Marin sells well, but only because the bikes are cheap.
Are we going to have to start sleuthing who manufactures frames for a given brand and try to connect the dots which eastern manufacturer has good QC and which one doesn't? There are LOADS of QC horror stories floating around there and it's not just broken frames (which can happen due to a bad design, causing some stress risers). Lately I've been hearing explicitly horror stories about alignment and general QC issues.
I would take the past 2 year of QC issues with a grain of salt. Western brands couldn't visit factories and check qc/assembly process until this last summer for Southeast asia, this autumn for Taiwan and just now of after CNY for mainland china. So we will see if the Marin is well made but the design is nice and simple.
Sram patent for a self-charging rear derailleur via a generator in the upper pulley wheel region.
I've been thinking a bit about regenerative stuff and bikes lately and keep coming back to the conclusion that it seems like the experience would only be good on e bikes where the motor can mask whatever losses there are. I'm sure the amount of power you'd have to pull to recharge a derailleur battery is quite small though. Something around 0.1 W if a 2.2 Wh battery lasts 20 hours. I guess if you really wanted to be fancy about it, you could have a brake sensor and only recharge the battery when the brake sensor is tripped and then do so at a much faster rate.
I was about to go on a rant about how implementing that in a pulley would make it more expensive. Then I remembered it's about electronic shifting. Now I'm going to sound like an old fart - what's wrong with cable actuated shifting??
While a bit harder to implement with Sram's layout (upper derailleur pulley actually makes sense on MTB AXS stuff), a friend of mine mentioned having a magnet in the crank spindle and some sort of an interface in the BB could work for Shimano's central battery concept of electronic system. You'd need a very small battery (CR2032 or maybe a bit bigger) and hold the charge in capacitors. And charge those with the magnet. It would work perfectly fine for road use as shifting isn't done as often (overall) as it can be on MTB and it's practically always done while pedalling (unlike descending on MTBs where you still shift somewhat, but put only a few pedal strokes in here and there in most cases).

Intense is still the clear winner in that category
The Marin DH shock looks short for 200mm rear travel, can't say the frame looks burly either. Budget DH bike market looks to be heating up though. Anything available now or coming soon that is close to the Tues Core 2 price? How about frames that are near the $2300 of the TR11?

I would guess that he's sized down frames given his style of riding.
Something interesting to note given @FullSend comments about Marin's build quality and frame alignment, that's a trunnion mount shock on there.

if its anything like the Alloy Alpine series the shock doesnt line up when mounted.
My frame got warrantied twice(Alpine XR) for poor hole drill alignment for the rocker into the frame.(one side was offset lol)
The shop got sick of it and checked all their store stock and they all had it, sent all the stock back to supplier. - they then replaced my Frame with anther Brand frame free of charge if i didnt want a refund(i took the other frame)
I've followed mark closely recently, Hes been using it at whistler etc the Instagram joke is the "black mystery bike" and from comments Hes made and now seeing Matt's it seems like you are right with being a "super enduro" or just a longer travel enduro bike that is compatible with a DH fork.

His whole idea about hydrogen powered cars is bizarre. Tesla is not researching this at all. Honestly I wonder what ideas he was bringing up to the new SC leadership that were continuously shot down. We may never get the other side of the story but I bet there is one. This is not to say I'm an apologist for Pon, but I'm not sure exactly where Robs head is right now.
Actually, Tesla is researching Hydrogen powered cars. Just go to YouTube and type in Tesla Hydrogen car and you can see several videos on that topic.

Not saying Marin doesn't have issues, I don't know them well enough, but all brands are currently a shit show when it comes to quality control because they moved to different factory's or were pushing to hard to get bikes out. Our warranty person in the shop had dealt with hundreds of brand new bike issues with year, from big brands putting Alibaba brakes on all their under $1200 bikes, all of the big 3 having sky high alignment issues one of which affected every single rigid fork on one of their commuters. Even usually high quality brands having brake mount posts being welded on crooked on their aluminum bikes. One that's started recently is someone's electronic derailleurs have poor tolerance and won't shift smoothly through the range.
Its been a terrible couple of years from brand and I hope we see things clear up soon because the sheer amount of wasted time and materials is embarrassing.

Onto tech rumors: When out on a lazy sunday ride yesterday, I came across a guy on my home trails who had what I can only assume to be a prototype bike with him, painted or wrapped in a black and white digital camouflage pattern. The bike had the unmistakeable silhouette of the Propain Tyee and Spindrift and since Propain is a local-ish brand to me, it's probably safe to assume that it was in fact a Propain. It definitley wasn't an e-bike, but a mountainbike, and since the Tyee is the oldest bike in Propains line-up, I assume that what I saw yesterday was the new generation. I'd say the frame was carbon because it didn't have any obvious welds. It looked quite finished aswell, so the release date might be not too far away.
Anyways, take it with a grain of salt. I only saw the bike for a couple of seconds while the guy took off his jacket and helmet and loaded the bike into his van. It could just have been a regular Tyee or Spindrift with a very eccentric paint job.

It's their first Horst-link bike too from what I recall.

It's good to hear from you.
It's Wheeltop EDS OX (Electronic Derailleur System)

They have not updated their website with a product page yet, and the software for it is in Beta.

You made me do a double take! I thought they had all been.
They did have a dual short link bike and the NAIL3D or whatever it was called too though, so not the first non-single-pivot FWIW.

I don't think the Marin has 200mm travel, I think it's more towards 170-180
Mark (who also rides for Marin) have been using it for at least 3 months now as a super enduro bike

Took some nerding but it leads to the SRAM AXS app
https://apps.apple.com/us/app/sram-axs/id1430049231
I thought we collectively agreed we'd never speak of that abomination again?
That crank looks disturbingly like the Race Face LP crankset I bought in 1992...

Oh good I'm not the only one who saw those cranks from NSB and went... "I have seen these before" haha
I gotta imagine the final design will be a little sexier and we are just seeing a proof of concept so to speak.
Didn't NSB make the original ones for Race Face back in day?
