Not surprised at all to see some people in this thread throwing tantrums. However they have to accept that it is very unlikely that the Vita receives a MH game any time soon. The incredibly poor sales and the very small install base make releasing what is typically a million+ selling franchise a death wish. At the moment even if the ENTIRE Vita install base in Japan bought a MH game it would still end up with poor sales for the franchise.
Personally though I'm actually far more excited about E.X. Troopers. It looks pretty awesome and I love the LP series.
