UFC 155 hasn't been formally announced by Zuffa as of yet, but the annual New Years event is pretty much set in stone. The main event will be a rematch between current champ Junior dos Santos and former champ Cain Velasquez for the UFC heavyweight title. The two men originally met on the first UFC on Fox card last November, where JDS scored a quick knockout victory over the AKA stalwart to claim the belt. They'll meet again on December 29th in Las Vegas, and promo master NickTheFace has put together another one of his stellar hype videos for the biggest heavyweight fight of 2012.
