Who knows when Gran Turismo 5 will ever come out? While some are suspecting a surprise early launch for the game, Polyphony Digital's penchant for long development time has us suspicious. In the interim, there's one reason a PS3 owner will want to check out Gran Turismo on PSP (besides the fact that it's portable): the ability to transfer cars from the PSP game to the upcoming console game. That should be incentive enough for collectors to try and "catch 'em all."
The video also details the various Ad-Hoc multiplayer modes: Standard, Party, and Shuffle. Although a mode named "Party" makes us Gran Turismo with green shells, the franchise isn't toning itself down for casual gamers just yet: this mode simply balances the playing field by sending more skilled players farther behind. No lightning bolts? Boo.
