I think it's not going to happen.
If there is a 5th fight the rivalry between these two will be even more inconclusive if Pac wins. I'd still buy the PPV though if it were to come up.
I think it's a given that it will happen. They both want it, and it was extremely entertaining. Plus, it is still the best fight out there. I just hope Pac's chin isn't cracked and we can have another FOTY. A tune up first would be recommended.
Everyone here knows they would watch it and love it.
On one hand I think Marquez settled it. The first 3 decisions were disputed and Marquez left no doubt in the 4th.
That said, I still want to see a 5th fight after what I saw last night. It's probably more buzz for #5 than there was for #4.
