Speaking to VideoGamer.com at Leipzig Games Convention 2008 Sucker Punch Game Director Nate Fox hasn't completely ruled out the studio making a PSP game in the future.
When asked if the studio has looked at the PSP as a platform for future games Fox stated that "Right now we're working on the PS3". Not much to go on there, but Fox did reveal that he's a big PSP gamer.
"PSP is pretty exciting," he told us. "I spend a lot of time on the bus, so it'd be nice to contribute to gamers around the world who also play games on the bus."
Could that contribution be a new Sly Cooper game? Only time will tell. For more from Nate Fox head over to our full interview.
