In a most recent interview ith Kotaku radio, Todd fully admitted that he wasn't sold on the animations in the games and said it could be better. If a company addresses where they went wrong, they probably plan on fixing it. We already know, due to various sources that Bethesda's next title is going to be natal based. I honestly believe it would be a lot easier to develop software and technology for a game that involves heavy melee combat, rather than a shooting game like Fallout...
He didn't just say they knew the animations weren't that good, he said that one of their
focuses is fixing the animation system for the next game.
