"I can't deny that we've had some challenges, but I think those are all behind us," he said. "It's all about software now, it's not about hardware. It's all about services, it's about the way the industry is changing and the way we hope to be taking a leadership position in that change." Harrison's comments came in an interview following his GDC keynote speech, in which Sony unveiled the new PlayStation Home service and exclusive title LittleBigPlanet - both of which have been well received by gamers and critics.
