Sony announced on Wednesday that its next-generation portable gaming console, the PlayStation Vita, will launch in Japan on December 17th. Sony also said it has teamed up with Japan-based wireless carrier NTT DoCoMo to provide 3G connectivity on the device. 20 hours of 3G service is priced at $13 while 100 hours will set customers back $65. The system will launch in tandem with Ultimate Marvel vs. Capcom 3 and Square Enix promised to port Final Fantasy X as well. Sony expects to begin taking pre-orders for the Vita on October 15th and said the first 500 units sold will come bundled with 100 hours of free 3G connectivity. We had hands-on time with the Vita during E3 in June. It is expected to launch in the U.S. next year for $249.99 and AT&T will provide stateside 3G connectivity.
