Fallout: New Vegas will take place in 2280, 3 years after the events of Fallout 3 and 40 years after Fallout 2
According to backstory Las Vegas was not damaged as much as the rest of the US so most buildings are still intact including the hoover dam which is likely to be a large part of the main quest as whoever controls it controls the water and the electricity.

EDIT
I probably should have noted that this game is being made on the Fallout 3 engine by Obsidian Entertainment under the commission of Bethesda Softworks because they're probably busy doing other projects.
