Sony PSP advertising hits the streets

Looks like Ken Kutaragi's been "getting up" on the streets of New York, Philadelphia, Chicago, and San Francisco where a series of PSP-inspired graffiti art has been spotted. The chalk drawings and posters illustrate cartoonish looking children playing with oversized PSPs.

So is this a legitimate Sony marketing campaign perfectly timed for next week's holiday shopping rush, or the workings of some carefully-coordinated, underground PSP-loving cult?
