Sony just announced at their Leipzig press conference the PSP-3000 series. It will look exactly the same as the current PSP-2000 (Slim & Light) model, but will add a built-in microphone and enhanced screen. Apparently, the screen will work better outdoors, being able to resist glare. The built-in microphone will be a huge plus for regular Skype users, and those that take their PSP online via Infrastructure.
Video-Out has also been enhanced, with the system now able to interlace for televisions that don't support a progressive output (that means non-HDTVs).
The PSP-3000 series will be available on October 15th in Europe and will retail for €199. There will be 8 bundles, each adding one game to the package.
