Diablo III Senior Producer No Longer With Blizzard

In a Tweet posted a couple of days ago, Diablo III senior producer Steve Parker reveals that he is no longer with Blizzard Entertainment and, as such, is no longer part of the D3 development team. No reason is given for his departure, however:
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.
Another crazy entry in the development timeline for Diablo III that tracks all the way back to, what, 2004? And if you think you have what it takes to replace him, feel free to apply for the job.
