Will there ever be a Jak game for PSP?

I mean come on, Daxter had his own game, then came Ratchet and Clank:Size matters, and now even Clank is gonna get his own game.

But can we get a Jak game? I mean I would love to carry one of my favorite games around with me everywhere.

I heard last frontier would be the Jak PSP game, but there has been no word on it yet.
