If Pac wins then he will have to choose between Hatton, Mayweather, and Marquez IMO.

I think another immediate Marquez fight will delayed because they don't want to make a transition from 147 to 135 right away.

If Hatton wins, then a fight with Pacquiao would be very possible, if he loses, then it's down the drain.

Pac and Roach only took this fight at welterweight because De La Hoya is old. I doubt they will want to stay at this weight and fight the in his prime, rightful champion in Mayweather. I just think they'll get lured into the fight because it would be a massive fight. Pacquiao also seeks the legacy cemeting fights and Mayweather would be just that challenge.

But like I said before, all this hypothetical talking is IF he beats De La Hoya. The picture changes if he loses.
