Over on the Capcom forums fans were talking about bringing Monster Hunter to the Vita, but quickly shot down. Sorry Vita dudes :-/
To which they replied:
There are many people that want a version of Monster Hunter for our PSVita... Capcom would win a lot of money releasing a MH title for Vita and woul make happy many people.
Please we need a MH in vita

As mrk1976 said, however, MH Freedom Unite is up on the PS store.
