Slightly misleading, they don't actually run Racket on the PS3. IIRC, they created a DSL for game logic in Racket and wrote a special compiler for that DSL.
That's still a good example of a "real" program written in Racket, but it doesn't prove that Racket is a good choice for programs that need all the resources they can get.
