The game will use Fallout 3's gameplay style, that's known for a fact.
Are you kidding me? FO 1 & 2 gameplay would be so horrible I'd rip my eyes out just so I can't see it. FO 3 gameplay FTW.
I'd prefer Fallout and Fallout 2 gameplay any time. Unfortunately, Bethesda is the publisher so it's not something they can do, even if the original devs who are making it would want it to happen.
Fallout 1 and 2 where both great games, but ide rather not have New Vegas in 2d
No one would want it to be 2D, this is just silly. Van Buren, the canceled Fallout 3 by Black Isle Studio, made by many of the makers of Fallout: New Vegas, was 3D and yet had gameplay style just like FO1/2 (aside from letting you choose between turn-based or real-time modes). However, it would be great if there was a top-down camera option, like in Dragon Age.
