“The current TNA lawsuit has everything frozen for the moment. WWE will not even internally discuss Sting. That just won’t happen. Until this lawsuit settles, finishes or is dismissed, there’s no way any discussion about Sting is going to happen. His name has never come up, and I can practically guarantee you that it won’t.”
The source also added the following…
“The idea of Sting vs. Undertaker, Sting vs. Punk, or Sting vs. Cena was something a lot of the young writers were dreaming about until a senior member reminded them there’s not a chance of it happening this year.”
