Psp is supp come out around june. (expect late spring-early summer)
The graphics engine actually rivals the PS2 making it the third strongest system out there after the GC and Xbox in first. The screen is too big and doesnt have the support it needs. (imagine the difference of falling into a normal tv and a normal tv with a flat screen and u will know what i mean)
The PSP is going to be like another PS2 but portable so I say, dont waste your time on it, get a DS.
