Do you ever think maybe you should spoiler block spoilers in a thread not tagged spoilers?I wonder what ending season 2 will go with for it's depiction of Vegas.
But like, ignoring that, I think we can probably deduce this or at least limit the possibilities.
Here are the endings for New Vegas (big New Vegas spoilers obviously).

Fallout: New Vegas endings
Fallout: New Vegas endings are determined by the player's actions and choices throughout the game and depicted on a Imageshow at the end. Most choices made during the game are not reflected and merely implied, however, such as the fate of Westside, while others are shown during gameplay or...
(Have to use a different kind of spoiler block for that so people can click on the link!)
Possibilities:
1) It seems very unlikely it would be an NCR takeover, given Moldaver was a higher-up in the NCR, and very much opposed to Hank McClean. So he wouldn't go there if so. Also the NCR would have probably changed up how the place looked, and de-casino-fied it.
2) New Vegas does not, from the two images we saw (the distant view, and in the end credits), look like it's changed significantly.
3) Independent is possible, but would probably mean creating a canon Courier character to rule New Vegas, and also I think there's no obvious reason for Hank to go there if so (given the Courier isn't part of the pre-war clique and nor is any other likely human independent ruler)
4) Mr House ending is absolutely possible. Mr House seems like he'd be a direct "ally" (with some light backstabbing) of the pre-war clique, and certainly his whole deal is similar. Perhaps too similar? But I think it's quite likely he's still in charge and if we see someone like George Clooney has been cast for S2 we will know lol.
5) Caesar's Legion. I think this is very unlikely, but it would be completely nuts and amazing, and I definitely can't rule it out, because I feel like the writers would absolutely enjoy messing with the insanity of Caesar's Legion. However - I think they'd have expanded far and fast if they'd got New Vegas, and we'd have heard about the, or at least seen something like an aquila or SPQR thing above New Vegas, were that the case. Also heavier fortifications. And maybe Caesar's Legion is just a little too thematically similar to the Brotherhood of Steel to be introduced so early - later on, when the differences would be more obvious, it might make sense.

So my personal guess would be Mr House ending, Courier is MIA and referred to only in vague terms, or, almost equally likely, Mr House ending, Courier is debauched and hopeless, lazing around the casino (probably will cast someone interesting as the Courier if so). Hank McClean 100% seems like he'd work well with Mr House (but also totally get betrayed by Mr House).
If we're making this a spoiler thread period though maybe we can just edit the title and I'll remove the spoiler blocks?
