It's probably going to be expensive, mabey $500 b/c it will be a smart phone/ game machine. Also, judging by the Iphone's quality of games, the PSP2 probably won't be wowing with graphics like the PSP has. I expect a lot more casual and smaller games on the PSP2 if Sony won't be able to find a decent processor at a reasonable cost that can do both games and do the processing needed for phones.
Mabey Sony will talk wtih apple to let them use the Iphones new processor or something
