The game that might be the Vita's Monster Hunter saviour type thing will be out on 7 March in Japan (the same day as Monster Hunter 4, chortle) in a new demonic bundle with a 4G card, custom case and neat red design with matching ear buds. There will also be the basic game and a dual pack to encourage multiplayer among friends. A demo is due out before the end of the year.
Is this "the one"? We'll see, but it will take a mighty effort to pitch this into a market that seems to be losing interest in anything non-3DS at pace. It would also be good to see a western release soon after to catch the wave if it does take off in Japan.
