Hell no
I got a PSP Slim last Christmas so I had something to do at airports. They release like what, 1 game a month?
Sony's goal with the PSP is to try and copy the app store. What they should have done was put in a second analog stick, which is what everybody wanted. Instead they took the same PSP, made it look uglier, and gave it a stupid name
PSP's are gonna be a dead product in a few years
PSP Go is a stop-gap product designed to compete with the DSi (ie. incremental feature upgrade, make it look new). Float the idea of digital dist. around to see if people take to it without risking a hell of a lot since people can always just buy a PSP-3/4000. If it does well, then they can move forward in a certain way on PSP2 (which sure as hell better have two nubs). If it bombs, then maybe they take a different approach.
And saying it's going to be "dead" is silly. It has sold almost as many units than the PS3 and 360 COMBINED, and it's only been out a year longer. The only reason it's sales are looked down upon is because it's competition is ****ing sales monster.
