User blog comment:SimpleStar010/Kut Ku confirmed for MH Portable 3?(links inside)/@comment-1520318-20100605213807

I think the second link is only a user poll of which monsters people want to see in MHP3rd. Basically, the TOP 10 most wanted.

That still does not confirm it will be in the game. Although there's probably a good chance Capcom will put it in to satisfy the fans.
