The company recently revealed it has begun prototyping a new IP, so its likely the culmination of this project will be an Xbox 360 exclusive. "Microsoft have been good friends to us," wrote production director Jonty Barnes. "You can see the strength of our relationship in Halo. We're really focused on continuing our collaboration in making the best games we can, and that right now is on 360."

Bungie's negotiations with Microsoft give the Redmond computer giant a minority equity interest in the studio, control of the Halo franchise, and publishing rights to Bungie's other products.
