Phantasy Star Nova and Digimon are other two games that could be released next year. But the first depends on SEGA's mood and the second one on the sells of SAO and Tales of Heart R, this could end with God eater 2 releasing if Freedom wars proves tobe slighty popular between Vita's small market on the west.
And there's Toukiden Kiwami/Extreme, the first one seems to have sold well for them on the west (at least Tecmo-Koei were glad) so is highly probably...
Lots of games to look forward, I would be more positive about all of them, but the lack of support from SONY made me negative about the Vita on the long term. I really can't see little publishers supporting it beyond 2015 in the west. Sorry for being so "Doom and gloom" but SONY pretty much have killed Vita this year...
