I find it hard to accept basically anyone else developing FALLOUt. And Bethesda is NOT great.
The thing that BlackIsle had going for them was that wacky sense of black humour on top of everything else. If the xbox/ps2 title is anything to go by, they don't get it. Even Fallout tactics didn't get it.
I doubt anyone @ bethesda can do the series justice. Its now just about post apocalyptia, its about the humour and grimness and the coolness and weirdness (and odd hitchhiker references)
