I definitely see them fighting at least 1 more time.
I think as long as they can hype up the fight, they can continue to schedule matches with these 2 fighters. I'm one of the only few who had Edgar winning the first time, but almost everyone thinks he won the 2nd time.
I'd really like to see a 3rd match, but I don't know if there'd be more than 3. If Edgar won a possible 3rd fight it would be controversial due to the fact that Bendo got the nod in the 1st 2, so there might be a possible 4th lol, who knows.
