Pretty tough question to answer given the long stretches of inactivity Floyd has, I'd think he will have more fights than people will expect him to have though.
Thats kinda what Im thinking too, with all the layoffs/retirements, he may have more left in him than expected.
Ortiz, Khan, Pac then retire until he's broke then comeback 3 years later and maybe win a significant fight or 2 and retire again then come back another 3 years later and get his ass beat a retired for good. he'll keep coming back til he loses and he'll be broke so he'll have to keep on fighting way past his best and lose to guys that couldn't hold hius jockstrap
