Naugthy Dog would like Uncharted on PSP

Evan Wells from Naughty Dog told Examiner in an interview that they would "love to see Uncharted grow beyond the PS3. It would be interesting to see what sort of changes to the design one would make for a portable system. But right now we are purely focused on PS3 development so we can’t promise anything from us in the near future."

What he does promise is another Nathan Drake PS3 game some time in the future.
