Seriously, who cares, they both should do well enough.
The only thing that interests me about Floyd vs Ortiz, is what Ortiz will bring to the dance, Mayweather's inactivity over the last 5 years might give Surfer Vic the edge he needs to win.

As for Marquez vs Pac, I see this as pretty much one as a onesided beatdown, Pacquiao is a much better, stronger, more talented fighter then he was the first 2 times they met, and Marquez is not.

I'll be watching both fights on a stream.
