What's with all the Mayweather-Mosley hype?

It's just the former pound 4 pound king, undefeated in his prime, vs. the most dangerous opponent out there (Mosley>Pacquiao, let it be known). Mosley is really the only #1 P4p fighter Mayweather has fought..the list goes from Jones-Mosley-Mayweather (correct me if I'm wrong). Boxingscene has not updated anybody on anything to do with the fight. Without an extensive search on Google, nobody would know the fight is ALMOST A DONE DEAL. ESPN barely has anything to do with the fight or the negotiations. I've been expecting to hear about this fight for some time, but it seems nobody wants to speak about it. Hype the negotiations at least!! (after the whole Pacquiao deal). Personally, I thought Pacquiao-Mayweather would be a letdown because I know Mosley is a better fight (and it should have priority, from a boxing fan's perspective), but that Pacquiao is a better fight for boxing (because it puts the world's spotlight on boxing).
