That's right, the Go! doesn't have a UMD drive -- games will instead load in through the Memory Stick Micro slot or over PlayStation Network. That's not the end of the classic PSP, though -- Sony says it will "live on." New PSP titles will be distributed through both UMD at retail and online simultaneously -- Sony's beefing up the desktop client and renaming it Media Go for easier access and syncing with Playstation Network media, but you'll be able to get PSN content directly from the Go as well.Sony said the Go! will debut for $249 on October 1 in North America and Europe and November 1 in Japan.
