PSP 2 or PSP 4000 I really hope that Sony finds a way that we can all keep playing the games that we already have. The strong game line up for 2009 in indicative that such will be. Also, can Sony risk losing the PSP install base that it has when coming out with a new product? It would be great if any game coming out for the new system would work with the older psp's. The only real problem that I forsee with that would be the addition of new controls on the newer psp model. I know that we could certainly use a right analogue input for shooters and such.
