Who will Manny Pacquiao fight next?

I know that everybody is drooling over a Mayweather vs Pacquiao bout to settle the p4p talk. but whoever wins the FM jr-JMM fight is gonna have to wait. do you think pacman will wait until all the way til december prob to face the winner of the Number One/Numero Uno fight or do you think he'll have a tune up fight during the summer/fall, you think?
