SO when Sony dose some server side things next week
the PSP will NOT be able to use the PSN store to download games right from the PSP
you will be able to use MediaGO and/or a PS3 to get the PSN games (from the PSN store) on to your PSP
so, It basically means that the ability to add content wirelessly from their PSN Store onto your PSP will be removed
