I just hope Larry Merchant doesn't become a commentator, he needs to retire badly.
Probably won't though. Jim Lampley (*main boxing commentator) has been openly against MMA for quite some time.
As far as boxing goes, it'll take all of its breath away. They'll see after they do two shows you watch. The 3rd HBO UFC PPV will do better than all of the boxing fights in that year unless it's some super freaking mega fight. Boxing has lost almost all of its steam. (Coming from somebody who used to watch boxing PPVs religiously.)
