God I hope not. They have enough teams to have 2 if they really try(hell the amount of quality teams on SD are more than enough). And I HATE the idea of combining the roster again. It doesn’t make sense for Fox to get Smackdown, make it live on Friday nights, and have to share talent between USA and Fox. They aren’t going to want to advertised a champ that basically only shows up on RAW.
Heck, SD Live has worked hard to really become a better show than Raw almost Weekly. Would hate to lose that just to keep the roster the same. Their is too many people on the roster already to go back to a combined roster.
