PlayStation 3 firmware update are improvements to the console's Remote Play functionality, though we'll need to wait until the PSP's 3.50 firmware update drops -- sometime this week -- before samplings the goods proper. Yet still, we're able to sneak a glimpse of the forthcoming update by selecting "Remote Play" from the PlayStation 3's "Network" menu, resulting in a screen that reads: "When connecting the PSP system over the Internet, you must sign in using your sign-in ID, "email@example.com", on the PSP system."
Are we looking at the first signs of a universal ID for the expanding PlayStation Network? Perhaps a single friends list that will follow you from device to device? Throw in that "long overdue" PSP-based PlayStation Store to download those PSone classics sans PS3 -- or maybe some videos -- and you've got a deal.
