Keep an eye on Conor McGregor too, typical Irish gob on him but simply brilliant, he's bringing back the hype they created when Lesnar signed.
Decent Promo for him:

The sport in general just keeps getting bigger, I'd like to think Foreign tv deals (Setanta/ESPN/BT) combined with Lesnar and the simple fact, there's no constant dodging in MMA, you fight the contender. Title fights are not cherry picked, they're all elite top level fights.
