Cool! It’s confirmed the PS Vita will in fact be region-free! That’s straight from the horse’s mouth — @yosp — Shuhei Yoshida, President of Worldwide Studios, Sony Computer Entertainment.
What’s that mean? It means when the Vita is released in Japan first, on December 17th, you’ll be able to import that badboy across the border and not worry about region locked games or content.

Import a Vita from Japan, buy a game in North America, and everything’s gravy, baby
