Inside Mac Games Newsbriefs is reporting that Brent Pease is no longer at Bungie Software. Brent was the project leader on Oni, Bungie's upcoming anime-inspired third-person combat game. Interestingly, Onicore dot com has more on this, posting the official press release that they say they copied from IMG (though I can't find it there at all). Here's what that has to say about this:

With the completion of the core components of the Oni game engine, Lead Programmer Brent Pease is leaving the project. Completion of the game design remains in the capable hands of the team, with engineering being managed by Senior Programmer Michael Evans, one of the founding members of the team. Oni development continues unabated, and new features for this unique action game will be on display at the Macworld Expo in January. The parting was amicable, and everyone at Bungie wishes Brent well in his future endeavors
