Sony has already shot down the rumor that a PSP2 is currently in the works, and that they'd rather focus on garnering more third-party support for the sleek portable.
But that doesn't mean they're sticking with the PSP-3000. According to Eurogamer, Sony has plans to issue yet another handheld update with the PSP-4000 in late 2009 (it's like an annual thing now), and the "true successor," the PSP2, will come at a later date. Citing "publishing sources," developers are supposedly already working on games for said successor, although Sony themselves "won't comment on rumor or speculation." Big surprise there. Anyway, it wouldn't be all that surprising to learn that this information was correct; the concept of yet another redesigned PSP isn't out of the realm of possibility, especially when some users weren't overly fond of the PSP-3000. The PSP-2000 – the upgrade that made the unit lighter and slimmer – really pushed sales through the roof for a while and after launching in late 2007, made 2008 the PSP's best year ever. The PSP-3000 also pushed sales, but perhaps due to what some just call a "weird screen issue," it didn't cause quite as big of a chart spike. What will a PSP-4000 do?
Obviously, with nothing official or concrete, we can't say for a fact that another upgraded PSP will release towards the end of next year, nor can we say the PSP2 is coming after that. It may sound logical and reasonable, but sometimes, neither logic or reason have a place in this industry.
