According to IGN Sony has officially confirmed that LocoRoco will be coming to the PlayStation 3. The game will be available as a PlayStation Network Download.
The PlayStation 3 version of LocoRoco has been rumoured ever since trophies from LocoRoco showed up in a teaser video for Sony's new online service Home a few months ago. The game is tentatively titled Buu Buu Cocoreccho! by LocoRoco. We ran the name through a translater and the name appeared the same in English, so don't ask us what it means.
The PlayStation 3 versin of LocoRoco will feature 200 LocoRoco characters in a new world. You'll be able to use the SixAxis for motion based controls and even though Sony hasn't revealed when the game will be available it is currently 95% complete, so the title shouldn't be far away.
