This is Capcom we're talking about, don't get your hopes up. A PSP version of MH3 would require too much effort for them considering that the source material isn't complete yet.
It's probably just MH2 following MHG's footsteps on the Wii. I would not put it past them to do it.
...that or Monster Hunter DS. Though I think they'd have cashed in on the DS audience by now if they wanted to.
