Although a lot of Fallout purists are getting riled up at the new format (I mean after all Bethesda made Oblivion...) from initial talks on Fallout 3 a lot are saying that it's not just Oblivion with guns... it's much much more. And now that Bethesda revealed some of the turn based elements of the game, it looks even more promising for the die hard fans.
Anyway, E3 is just wrapping up, maybe there's news on Fallout 3 coming out soon.
