You asked for it ... and now you got it! The PSP Extended Life Battery Kit will work on both the old and new PSP-1000 and PSP-2000 models. This 2200mAh battery will offer 20% more battery life on the older models, and 80% more life on the new slim line. This battery will bulge out slightly on the slimmer PSP systems, so new battery covers will be included. However, those with Star Wars
Ceramic White systems are out of luck: doesn't appear a new battery cover is being made for that particular model.
The peripheral is releasing in mid-December for a MSRP of $44.99. We'll have a hands-on in the coming weeks.
