Bob Arum's next step?

I know that there is a lot of threads going around, yet most of them only focus on Margarito (or Cotto to a certain extent). No poster seems concerned with the puppetmaster's next move. At this moment, Bob has to be pissed out of his mind, not only did he risk one of his bigger cash cows to him and spent a lot of time (and therefore money) trying to convince people that Tony was for real, but he also paid off a big time lawyer just to see Capetillo break any chance at defense by admitting his "innocent mistake". I strongly believe that Margarito's days with Top Rank are finished, Bob will have no problem turning his back on him now. There has been a lot of talk here regarding if Cotto's loss should be ruled a NC, regardless of the lack of evidence. I think only Arum has enough money and influence ($$$) to pursue such a case now, pushing his case on "reasonable doubt" now that the cheating has been admited. That would bring guys like Cintron and Clottey into the mix as well. Nevertheless, what do you think Bob will do? Backstabbing? Lawsuit? Other? (P.S. Please do not turn this into a beef thread.)
