The concepts of Nexus, New Nexus, and The Corre was good but the writers messed it up like usual. I dont think it will come back. I do think that some of the former members may run their own stable at one point.
It seems like David otunga is gonna be a major player in one of John Laurinitis' stables if he has one.
CM Punk may have one again but he's currently a tweener type of face that is sort of a loner, so no time soon for Punk. Plus, he has led enough stables so far, including: New Nexus or Straight-Edge Nexus, Straight-Edge Society(S.E.S), and at one point led The New Breed but he had a power struggle with Elijah Burke. Punk has been in the WWE for six years(not counting his one match against Val Venis on WWE Heat 2005) and in four years(2007-2011), CM Punk has led three stables. He should take a break from stables before that is the only thing people remember him as, a stable leader.
Ryback may have a stable of his own but appears as a loner.
Wade Barrett may lead another stable but he needs to take the loner path for a little while more and establish his place in the company. Also like CM Punk, he has led too many stables in a short time. He was on the main roster for two years and in his first year, he led two stables. Like CM Punk, if he doesnt slow his pace down with leading stables, he will be remembered as a stable leader.
Daniel Bryan has established himself as a main eventer and tends to be going down the same path as CM Punk. If he does the same path as CM Punk, it's almost a guarantee that Daniel Bryan will probably grow his beard a little longer, maybe shave some people hair or give them a certain look, recruit them, and lead a stable of a Vegan Society and also claim that he's a savior. May use Jesus like mannerisms to manipulate people. He may even be like a Vegan version of Undertaker in his Ministry Of Darkness days because CM Punk was clearly a Straight-Edge version of Undertaker in his Ministry days.
Heath Slater may lead a rock band.
Justin Gabriel may lead high flyers.
NO NEXUS will not reform.
I am interested in the idea of a new stable and if they bring a stable back, it should be the MInistry of Darkness led by Undertaker but he will not be a wrestler. This would make stars big.
