Monster Hunter Frontier G is coming to Vita in 2014 in Japan, and it will allow cross-play and data transfer between PS3 and Vita, Capcom announced at TGS. Monster Hunter Frontier G is slated to hit PS3 and Wii U this year, also in Japan.
Monster Hunter Frontier is an MMO first launched in 2007 on PC, and in 2010 on Xbox 360. Frontier G is an update to that version and is similarly subscription-based, even on Vita. The Vita version will not include every level of the full console game, but it will have "several PS3 worlds," Siliconera reports.
