Not anything big, but Emil Pagliarulo, the Lead Designer of Fallout 3, had this to say about the game:
I'm both incredibly happy and proud of the choices we've made in the
development of the game. Of course, you could argue, "Of course he'd
say that." But the truth is the truth.
I'm hoping for the best. It would be cool if Bethesda started interacting more with DAC and NMA, though, and not just "main stream" media.
