Sony Computer Entertainment Europe have announced that their PS3 kart racer, ModNation Racers, is also going to be available for the PlayStation Portable.
A similar move was undertaken with LittleBigPlanet, but unlike that scenario, the PSP version of ModNation Racers is set to launch around the same time as the PS3 version.
There isn't going to be much downsizing either - all of the creative tools will remain intact and you'll be able to share with the PSP community. It doesn't sound like there's going to be any inter-connectivity with the PS3 version in that sense, but that's to be expected. Players will be able to race against up to 6 other PSP players online though.
The game is tentatively due out this Spring, and if you don't have a PS3, you can apparently now enjoy it on PSP instead.
