The PSP Go was not a big surprise due to the overwhelming amount of leaks that happened over the week end. The Media Go however the big news, it is Sony’s “Itunes” that runs on a PC to sync content with the PSP, Sense Me the equivalent of Genius will display related content that users might like as well. All future PSP apps will be digitaly delivered via the Playstation Store. UMD title will still exist as not everyone want to download. (why??) The PSP Go is 50% smaller and 40% lighter than the original PSP.
