Not much solid information yet, but the current rumors say it is supposed to be a new top of the line XC fork a step above the SID.
Not sure what size wheel that is, but it looks like mud clearance won't ever be an issue with it!
If you zoom into the picture you can see a small rectangle on both sides of the fork crown. The current rumor floating around is that it will have some sort of electric lockout (Rockshox's answer to the Magura Elect?), so possibly a charging port? Or more likely, that is how you access the nuts to take apart the fork. There's also the possibility that the whole crown/steerer/lowers (or, I guess they're called uppers now) could be a one piece carbon fiber setup, which would definitely make it light, probably lighter than a sid by quite a bit.
Anyways, what do you guys think?
Ok, but seriously, unprotected stanchions on an USD fork is not smart. The amount of rocks, mud and other muck that gets thrown up at the lower portion of a fork is not ideal for a fork requiring unmarked stanchions to stay sealed and smooth.
How do you combat the legs twisting like noodles? Yet Another hub standard by the looks of it.
The pics on a 120mm bike with Hans Dampf's also point to a little more "Enduro" than XC race. If so, I'd guess it would be because the necessary weight to keep everything stiff bumps up the weight over a SID but is more acceptable to the trail crowd.
On a superlight hardtail frame it would look awesome. On a full susser.... it doesn't look aesthetically great.
Despite my cynacism, I am really looking forward to finding out the finer details.
I wonder if revolutionising the MTB fork market will be as successful for SRAM as revolutionising the road brake market

This is twice the fork the lefty is
But being serious, hub is 15mm thru-axel and those rectangular ports are for a lockout of some sort (Pinkbike did an article). Stiffness is the only reason inverted forks haven't taken over the suspension world as of yet, However for XC you don't exactly need the stiffest fork ever. DVO who is makes an inverted DH fork uses carbon shields mounted to bottom of the stanchions to protect them from debris.
Side note, I really hope they don't start specing stumpies with SRAM wheels
In the second pic, the bike looks like a Camber, judging from the forward shock mount and concentric FSR "rocker" link, which has 110mm rear travel and is 29er only. The SRAM Roam wheels are also AM level, so the front tire is a fit. Could be a 120mm fork. I also see yet another Avid rotor redesign.
Not too worried about rocks and dirt hitting the stanchions. I think they're safer there, than next to the tread. Might be a bit more susceptible to brush that is whipping back after the front wheel hitting it, but that's all I can think of that would really doing more harm to it than if it weren't inverted.
Paul Turner and X-Fusion have an inverted fork, but it's marketed as a limited edition made in USA AM fork, with lifetime service. They say the trick to improving torsional stiffness is using keyways in the slider, that way they can use round sliders and round seals/dust wipers and bushings.
Front hubs can go wider, and I wonder why they don't. It may be a new hub standard, but I bet they can make it backwards compatible, perhaps with a couple 5mm spacers on each end, if it's a 110mm spacing.

What would make you think that? To me the crown shape is very similar to heaps of carbon rigid forks. I'm sure RS would have no issues molding it seeing as the one piece crown/steerer on a SID would be in many ways just as challenging to manufacture.
