Honestly though, I'm intrigued. If it's a superstar, I can't think who it could be. Perhaps John Morrison? But then again, would WWE invest so much time into promoting Morrison's return? Unless he's going to b getting a big push I assume not. arrett than Cara IMO
Sin Cara, Rey Mysterio and Wade Barrett are injured superstars that it could be. Mysterio's suspended, so let's rule him out. It's more likely for Barrett than for Carra if it is indeed for a superstar.
The WWE network is still a long way away (I think they were aiming for November last I heard?), so I can't imagine it's for that.
I'm going to take a punt at it being this new Cruiserweights show. Although the show is for the Network, I think WWE will debut it as a brand/new show first to see how the audience take to it. Revolution being the new high flying guys getting a chance to shine. Could be that I think.
