This is a body blow for PS Vita no doubt. How severe a body blow will be determined somewhat by whether MH4 is exclusively 3DS or not. Precedent-wise has a MH game ever been multiplat? I seem to recall, this gen at least, that all the platforms with MH games have their own special brand of MH game. So if there's a MH for PS Vita it won't be MH4, if my impression of current gen precedent holds true.
Of course Capcom are known to share the MH love around (even finally deigning to give PS3 a MH experience, albeit a HD port of the PSP game, and not it's own custom made entry (less service than 360 got even!). So it seems likely that Capcom aren't going to completely desert the PSP fanbase, unless Nintendo paid them buttloads of cash to go 100% Ninty exclusive.
