Listen, when a developer says they want to go a certain route in a game and have the clout to do so I think it is a safe bet tis going to happen. Bethesda has the money and clout to do anything they want within one of their games.
They have a style and a style that their fans expect them to contineu in each of their in house games. I expect them to continue in that style for it is something they are comfortable with. Just because they have the Fallout license doesn't mean they are going to give up that style in which they present their games. I do not expect them to nor see it happening for Fallout 3.
I like Morrowind, and I know I will have a kick out of Oblivion, but just because I will enjoy those games and the style they are presented in doesn't mean I will automaticcaly enjoy Fallout 3 presented in the same style. It wouldn't be Fallout. I will support Bethesda as long as they make games I will like but from their style and the admission of those in charge Fallout 3 will not be a game I will spend money on.
