Probably not. I still firmly believe that the Nexus are going to be permanently disbanded at WrestleMania 27. No idea about The Corre, however, they could have a longer shelf life, which would explain why the WWE went to the trouble of getting new music for them, even when the previous theme Nexus no longer uses fits the group PERFECTLY, "We Are One" (mind you I'd rather have the new theme...) and they could've used that.
The groups are totally different. For The Corre, it's about trying to establish every member of the group as a valuable component. For Nexus, it's about taking 4 unbelievably green, poor talents and placing them under the leadership of the master of today's wrestling industry and praying to God that he can get them over.
