In what is expected to be the most significant hardware revision since the PSP was first released in 2004, the PSP2 picture seems to take a clearer shape with each passing week. Now, Kotaku claims to have confirmed some important details surrounding the highly anticipated handheld. The blog has apparently confirmed rumors with several sources that Sony’s PSP2 will sport a rear-facing touch panel. The panel is described as a “big mouse trackpad,” though details on exactly how it will be implemented are still unclear. The report goes on to state that the display on the PSP2 will be sharper than the screen on the current PSP, and it will also be 1-inch larger. Sony is reportedly describing the display as “HD” in private meetings. In slightly more troubling news, the company may be having overheating problems with its current prototype hardware, but release delays are not expected. Sony is said to be targeting a release date some time in fall 2011 for the PSP2.
