At 2007, Sony announced that a new version of the PSP would be released in September 2007, for all regions. The redesigned PSP is 33% lighter and 19% thinner than the original PSP. The redesign also features composite TV output, supports charging viaUSB, double the onboard RAM (32 MB to 64 MB), and has a brighter screen. It also caches UMD data in memory to decrease game loading times. The WLAN switch has been moved to the top where the old IR receiver was to avoid accidental switching, and the speaker vents that were at the bottom and underside of the original PSP have been moved to the top of this new model.
