We might not see much of any roster cuts. Between the Bellas leaving voluntarily, Edge's contract expiring, and the release of Goldust, a lot of funds are freed up. Jericho is leaving soon, which means guys may move up in the ranks as well.
Most of the guys debuting are heels, so they need faces to feud with. And since the new NXT consists mostly of FCW guys, most likely the low carders will be promoted and used to fill time on SmackDown or for the three hour RAW. We might even see the end of the Supershow and a re-enforced brand split. They do have the talent to pull it off, the talent just needs the opportunity.
