The PSP just recently underwent a redesign, and now we have a slimmer, lighter unit that has been selling very well. However, it can't last forever, and experts are already weighing in on the second iteration of the handheld. We have no idea when the PSP2 will arrive – or even if it will arrive – but it's always tons of fun to wonder and speculate.
According to Games Radar, a group of polled experts are predicting the PSP2 will boast a new interface, including a touch-screen, and Sony will drop the UMD support in favor of internal flash memory game downloads and "improved PS3 link-up." At this time, though, Sony has no plans to get rid of UMD and the experts agree the format is "safe for now." Besides, ever since the PSP-2000 hit, sales have been steadily climbing and there's really nothing to complain about. There's always room for improvement, of course, but the experts don't believe that the PSP, in its current form, "won't get any more major operations." Basically, they're saying there's no chance UMD will disappear until the PSP2 hits.
The experts appear to be split on the existence of UMD in the first place, as some say "it's useless in a digital world" (veteran developer Dave Perry), while others believe the UMD format "gives Sony more shelf space, something that might be keen to keep up with Nintendo (DS) encroaching on their space" (Gamasutra Senior Editor, Brandon Sheffield). But in the end, most agree UMD is here to stay…for now. The PSP2 is another matter entirely, though; it'll be interesting to see what Sony wants to do.
