@Robo: I am not sure about Vegas. I am a HUGE Fallout 1/2 fan, and was very disappointed in Fallout 3. If it had another name I probably would have enjoyed it more (Sort of like the Chrono Cross syndrom, tho I love CC). To this day I still think of it as Oblivion in a Desert with guns.
It is almost justice that the old founders of Black Isle Studio's (Who developed Fallout 1/2) get a chance to make New Vegas (as Obsidian now). I hope they put more effort into this game than they have some of their previous products.
