MW and LW were only ones without it I can think of. Now LW will have an interim one because Conor won't be back for a while. Even if he doesn't get the fight, he'll go on for months with the ruse that it will happen, he'll build up his name and then if it doesn't get done, he'll say it was all Floyd's fault, he's ducking him etc and will just use the fame for his next UFC fight and hope that it sells more than ever (will most likely be Diaz 3)
