A Sony spokesperson has told Eurogamer he believes that LittleBigPlanet is "potentially our biggest Blu-ray release of 2008".
Asked about Sony's plans for the Media Molecule game, marketing man Nick Robinson - a senior product manager at Sony Computer Entertainment Europe - confirmed the title will be released in September on Blu-ray disc only.
He left no doubt that Sony is giving the unusual, innovative mix of platform game and content creator the full blockbuster-release treatment. "This isn't a Warhawk or a Tekken: Dark Resurrection," he said, mentioning two games Sony has made available for download on the PlayStation Network. "This is a triple-A Blu-ray title."
Robinson felt that Sony's confidence in LittleBigPlanet was backed up by the overwhelmingly positive reception it's met with so far. He also confirmed the game will have a very substantial offline Story mode to justify the price for those less interested in its community and content-creation aspects.
Certainly, today's demonstration hasn't dimmed our own (massive) enthusiasm for LittleBigPlanet. Check back soon for full hands-on impressions.
