Diablo 3 Senior Game Producer Leaves Blizzard

Somewhat random and shocking news: Steve Parker, the Senior Game Producer for Diablo III has left Blizzard according to a Twitter update.

It's not quite known whether this is for personal reasons, or if he didn't agree with Blizzard's recent system changes to Diablo 3.
Hey Twitter, I'm no longer working at Blizzard or on D3. I've had a great 5 years there and those guys are going to kill it with Diablo.
Hopefully there wasn't any bad blood between Blizzard and Steve Parker, but by the looks of his follow up tweets, there doesn't seem to be. Perhaps this just means the game is ready to go, and he feels he is no longer needed, and thus moving onto future projects.
