During the E3 keynote, Sony briefly noted that they wanted to expand the PSN's "universal ID," and we asked Yoshida if that expansion could hit the PSP. We asked if using the same PSN ID from the PS3 can access a universal Friends list on the PSP. His response? "That's the plan."
Already, implementing the PLAYSTATION Store directly on the PSP is in the works. It won't be too long before we see even more features of the PS3 popping up on the PSP: Friends lists, messaging and who knows what else ... trophies, perhaps? Stay tuned in the coming days for the full itnerview.
