Midway was highlighting three forthcoming PSP titles at its booth: NBA Ballers Rebound, Mortal Kombat Unchained, and Rush. All three are PSP-ified versions of existing Midway properties, but Rush's origins may not be as explicitly clear: It features much of the arcade-style racing action of the original game--it's a portable version of L.A. Rush--but adds online multiplayer and a PSP exclusive Stunt Arena for some Burnout-like crashing mayhem.
Look for Rush in the fourth quarter of this year and Mortal Kombat Unchained about three months earlier. NBA Ballers Rebound, meanwhile, will hit the court later this month.
