Rockstar has officially announced two games for the PSP, set to be released around the time of the PSP's launch in the U.S. The games are (duh) Grand Theft Auto and Midnight Club 3. The Midnight Club 3 game is just a port, but the Grand Theft Auto game is new, taking place in Liberty City. And you and I both KNOW that GTA will sell.
