J.E. Sawyer is heading the development of New Vegas, he was the lead designer of van buren. NV is set in the same region as VB. It's safe to assume NV is either going to be a revamp of VB or will at least contain locations and concepts that were intended for it.
It's not really the same region, it's just a small part of it, as New Vegas will likely focus on Vegas and its immediate surroundings. A remake of Van Buren would need much more time than just 1 year. They will likely feature or reference some VB characters and factions, though. Regarding the poll option, Van Buren simply cannot be "a part of New Vegas", nor a FO3 DLC, given that story-wise, it was much bigger than FO3.
Leave it be. Van Buren was highly controversial when announced, due to changes made to SPECIAL and what I felt would be a rather empty storyline.
Empty storyline? What have you actually read about it and where? In my opinion, it was much superior to Fallout 2 or Beth's Fallout 3, although still not as good as FO1. And the main storyline was certainly bigger than in any of the other games, including Beth's Fallout 3. And you do realize that Bethesda changed SPECIAL much more than the VB devs ever intended?
And yes, if anyone should remake Van Buren, it's the original developers (currently at Obsidian), not Bethesda.
