"What publishers have said is they're not going to spend the resources on Wii... In my job, we compete against Microsoft and Nintendo, and we're competing for resources. So when I walk into a publisher, I ask, 'Where are you guys pushing your resources?' In the past, it was 'Look how hot the Wii is,' or 'Look how hot the DS is,' and 'We should put resources there.' They did that and realized, 'You know what, third-party product just doesn't sell on that platform.' So now they're taking those resources, coming back to us and saying, 'Sony we're going to be able to provide you with that exclusive content,' or 'We're going to put more engineers on it and figure out to maximize the Blu-ray and get more out of PS3.' That's what we're seeing now,"
