I don't know why anyone would think that Capcom would develop another MH originally for home console. Vita is far more likely than either Wii U or PS4. It's a series that has made its home on handheld because of the way that Japanese gamers play and interact. These games are designed to play on the train on the way to work, in the classroom during breaks, etc with ad hoc wireless. Japan doesn't sit at home and play console games in their spare time like Westerners do.
But MH5 on Vita would be unlikely too. It's too late for MH to sell as well on Vita as it does on 3DS. We're talking about nearly 6 million shipments in Japan alone between MH4 and MH4G. Maybe for the Vita successor, if there is one, but I'm not even sure that Sony will bother making a Vita successor.
