According to the latest rumors, the Xbox 360 will debut with roughly 15 to 20 games, with additional waves being released every few weeks. Many of the launch titles are thought to be next-gen sequels of established franchises. Topping that list is the long-awaited sequel to Perfect Dark, as well as a half-dozen or so racing titles, including Project Gotham, NFSU, Test Drive, a new Namco series, and the possibility of a Burnout installment.
