1UP - Sony is slated to reveal its PlayStation Portable 2 system sometime within the next 24 hours. The PSP2 has been the worst-kept secret in the industry for the past year -- everyone knows it's coming, and we have a pretty good idea of its features, too -- so it seems likely that the company has been holding back the official unveiling until the ideal moment to take the wind out of Nintendo's 3DS hype. This means, obviously, that the original PSP is on its way out the door. Rather than simply cry, "Good riddance!" with a firm hand to its back, we'd like to usher PSP to its retirement with a more measured appraisal of all the the console did that was both right and wrong. As a small bonus, we'll also offer our best informed guesses for how well Sony will duplicate the PSP's successes and sidestep its failings with its next-gen handheld.
