The Develop Conference & Expo is where the European developer community came together in Brighton from July 24th to 26th, 2007. It was there where for the first time the LocoRoco Cocoreccho (LocoRoco 2) trailer was shown.
Take a look at the first PS3 gameplay footage with up to 200 LocoRocos on-screen and under your control at once!
PS: As far as I can tell, you should be able to upload the PS3’s downloadable PlayStation Network game to your PSP for play. Although that’s not been confirmed, since the game uses the Sixaxis PS3 controller’s motion controls for movement.
