Kotaku reports that speaking to a reporter’s gathering this morning, when asked about the possible introduction of some internal memory in future revisions of the PSP, Tretton stated:
"I think we definitely thought about it. I think that's the trend moving forward."
He also spoke candidly about the firm’s portable disc format: "I think the UMD has struggled, and that's an understatement. That's been a very frustrating thing. I don't think UMD movies were handled very effectively."
