The official announcement of PlayStation Vita's Japanese release date will "probably" happen at the Tokyo Game Show next month, Sony's said.

TGS is set to be held from September 15 through September 18 at the Makuhari Messe in Chiba, Tokyo.
Yesterday - just as CVG told you first - Sony executive vice president Kaz Hirai announced a 2011 release date for PlayStation Vita in Japan, but confirmed the handheld won't hit Europe or the US until next year.
Sony had promised a "phased global rollout" starting later this year, and our sources indicate Vita will hit western markets in January or February. When it does launch in the UK, Vita will set you back £229 for the Wi-Fi model and £279 for the 3G version.
