Well, maybe if Obsidian are contracted again he'll be the lead project director.
(or whatever it is that J.E Sawyer was on FNV.)
MCA has said previously that one of his personal workrelated desires is to lead a Fallout game. I'd so want to play that game. Not to undermine J.E. Sawyer, he did a great job with what he was given (although, I do believe he could've done even better with little more time), but if you compare answers given by Sawyer and MCA (in different interviews), you'll notice that - while both are professionals at this trade - MCA tends to have the "righter" and more defined answers as far as RPGs go.
I really do hope, Obsidian is given another go. There's no other developer in the industry that could do better ---- except fo maybe Piranha Bytes or CDProject RED, but even those are doubtful.
Here is something I noticed may be a clue to it or something.
=====================
As far as the public knows, New Vegas marks the end of your involvement with the Fallout franchise in the near future. How do you feel about that?
Sad, but hey, it’s happened to me before with Fallout at Black Isle, and this time, it goes out with a bang in Lonesome Road… if you want. It’s nice to be able to put down the punctuation mark at the end.
Some conclusion to be had at the Lonesome Road. That's good to hear.
