Sony's just announced in Tokyo that the PlayStation Vita will debut in Japan on December 17th, and it'll partner with NTT DoCoMo for the console's 3G service. Customers will have two choices of connection here: 980 yen for 20-hour prepaid data plan, and 4,980 yen for 100-hour prepaid data plan. Alas, the rest of the world will still have to wait until 2012, but you'll know more concrete dates as soon as we do. For now, head over to our sister site Joystiq for the SCEJ press conference liveblog.
