A quick dig into Namco's latest financial figures shows God Eater 2 as its No. 2 video game property, selling some 700,000 units across PSP and PS Vita in Japan alone. As it should, considering it pissed all over CoD Ghosts. With a recent update adding full multiplayer, a western release is maybe a little more likely, but don't hold your breath.
Dragon Ball Z Battle of Z isn't too far behind, which suggests further portable versions in that series (and it already came west). Knock yourself out with the full PDF here. Given the rising portable sales in Japan, wonder if they'll consider a Vita Dark Souls title or spin off?
