Superannutation have found that High Impact Games' lead animator Justin Rasch's website lists a new Crash Team Racing as part of his work experience. The game is listed as a prototype for PS3, Wii, and Xbox 360. However, the fact that it's listed as a prototype suggests it may never have left that stage of development, and the lead animator seems to be looking for a new job.
High Impact Games are best known for their PSP efforts with Ratchet & Clank: Size Matters and Jak & Daxter: The Lost Frontier.
