Here is a quote, in the Youtube comments, from a dude who said he was once on this project. A later quote from the supposed ex-lead designer commented afterwards confirming the story. Split for clarity.

"FYI, the project's all smoke and mirrors.
Me and a friend were part of the team early on after it became a thing (I was a mapper, he was the lead designer.) but then there was tension between him and the project lead because he was questioning some of their creative choices; the plot's basically just The Magnificent Seven with an ersatz NCR-Legion conflict and the team was just obsessed with making every character a woman if possible for the sake of being 'progressive'.
One day he decided to vent some frustrations about the issues with the project to the editor in confidence, who proceeded to snitch the entire conversation to the project lead. Despite it being actual critique, my friend for the boot for asking questions. Of course, since he was the lead designer, this kinda fucked over the rate of progress they were making with fleshing out the project (Meanwhile the editor got promoted to manager as a reward for telling.)
You know what's funny? The single map I made is probably the only ingame thing related to this project that's been made since 2013 when it started. It's all just concept art and scenarios - nice looking concepts, yeah - but there hasn't been a single game asset made yet. The project lead got a tad pissy when my friend called him out on that and said he was gonna go to the GECK right away to make something... which he never did. I don't even know if it's supposed to be a NV mod or a standalone game and I don't even know what engine it'd be on.
That's not even mentioning their honestly disrespectful attitude with people with actual technical skills. They just expect people who can map, code, script etc to just work and do everything they say with zero input - I couldn't even get into an involved discussion about they wanted when I joined to map for them, they just dumped a google doc of concepts of me to go copy off. One of the guys in the team who was getting treated like this tried contacting my friend after he got kicked to get his side of the story. The team heard about this and kicked that guy too.
They're basically riding off the fact they've got Avellone's 'blessing' and they're trying so, so hard to look like legitimate game developers. I'm not sure what to think at this point but I'm really not gonna be impressed with anything they do until we see an actual game come out of it, even if it's just a bunch of shitty model renders or a super WIP map."

Typical drama.
Interesting if true though. I wouldn't hold my breath for this to get completed, although the concept art is impressive...
If it makes any progress most likely it will switch over to Fallout 4 once it is finished.
I've seen a better Fallout concept set in Texas that Dutch Ghost has talked about for some time now.
