One area where Sony's gaming division is excelling in is the PSP. No matter which way you look at it, the PSP is doing great, and Sony wants it to do even better. Thus they have announced that within the next few months a new model will be available.
The PSP-3000 doesn't have any cosmetic changes to it, but under the hood has some significant improvements. They've added a built-in microphone, upgraded the display screen and made Skype a default package with the unit. The microphone probably has something to do with the inclusion of Skype.
The PSP-3000 was originally rumored early this year, around March, though wasn't "officially" confirmed until just recently.
