The other big rumor is that a new disc-less PlayStation Portable is in the works. I think this new PSP will be shown, and hopefully be quite small, with controls that slide out. It'd be nice if it featured dual analog sticks, but I wouldn't even place even money on that.
If a new PSP is announced, and it doesn’t have a UMD drive, Sony will have to show consumers that they’re allowing the entire PSP library to be played on the device.
