As others have said, God Eater 2 should do very well, though certainly not on Monster Hunter's level. It's a franchise with an identity and one that hits a lot of the switches the Japanese like--hunting, anime-type characters, and pretty girls with strange outfits. Personally, I'm much more interested in God Eater than MonHon, which has never appealed to me very much.
I think the sales numbers will be good enough to make Capcom regret not having a Vita Monster Hunter title.
