He was on Twitter a bunch until Fez released, and then just stopped. Where did he go?
EDIT: I'm hijacking my own comment and saying that I've always liked Phil Fish. He seems just as loud-mouthed and arrogant as the Penny Arcade guys, but chose the wrong time to make a big deal out of something. He also might've been a tad bit immature about it.
P.S. In the special edition of Indie Game: The Movie, there is apparently a "Phil Fish Epilogue". So I guess they filmed something after FEZ was released?
EDIT AGAIN: I hate the Internet. We could have had Fez II you fuckers! Why'd y'all have to screw it up? I hate you all. Also, the "Special Edition" of IG:TM just got released and The Phil Fish epilogue is great. Makes the recent news even worse.
