Both these fights will happen in 2009... Ill explain why.
There was no interest in a rematch right after Floyd beat Oscar and Oscar wanted an rematch and still does. As of next week Oscar will have back to back wins and a rematch with Mayweather will make more $$. Mainly for two reasons. Oscar will look good Saturday to the public, and people will wonder if the time off hurt Mayweather. It will be deemed a pick em' fight by most Oddsmakers and boxing fans.

On to Pacquio. He will lose Saturday. He will hang with Oscar though and gain respect and interest in a Hatton fight by the public will be stronger than ever. Pacs stock will remain high and Hattons stock went back up after dominating Malignaggi. The fight will happen at Light Welterweight.

I also believe the winner of the two fights will likely face each other in yet another big PPV event. 2009 is going to be huge money maker for HBO fighters and a safe one. Im noticing a trend where Oscar, Mayweather, and Hatton never cross paths with Margarito, Williams, and Cotto and I dont see that changing anytime soon.
