The WEC's Reed Harris confirmed today that Urijah Faber vs. Jose Aldo will take place on PPV sometime in May.
I've long been a skeptic of the WEC's prospects for PPV, but I understand why they need to start running PPV events. If they can't succeed on PPV they won't be financially viable in the long haul, and they can't count on Zuffa subsidizing them just to keep Versus occupied forever. However, May is a bad month for an obvious reason: there is way too much competition for the WEC to succeed in May.
Take a look at the tentative PPV schedule for May in the United States:
May 1: Floyd Mayweather Jr. vs. Shane Mosley
May 8: UFC 113--Lyoto Machida vs. Shogun Rua, Forrest Griffin vs. Antonio Rogerio Nogueira
May 15: (Presumably WEC)
May 23: WWE Judgment Day
May 29: UFC 114--Rampage Jackson vs. Rashad Evans
Three major events will already strain the wallets of fight fans in May. WEC should wait until June, where a single UFC card in Vancouver is all they'll really be competing with, and it doesn't look like that card will have anything big in the main event slot anyway.
I'm rooting for the WEC to succeed on PPV, but I'm also realistic. I know that if they completely bomb, they probably won't try again, because it's unlikely they'll have a bigger fight than Faber-Aldo anytime soon. There's no reason to make success any less likely than it already is by squeezing the event between massive UFC and boxing shows.
