"- WWE released financial data this week that revealed Shane McMahon has not signed a contract with the company as a performer and he has not been hired for an executive role. WWE expects to pay Shane in excess of $120,000 for his role as a performer leading to WrestleMania 32."
No way Shane Mcmahon would neglect his other business ventures and become a full-time on air talent in a long term program following wrestlemania where he would pretty much play the boss of the company for a measly $120k. Clearly his run with the company is ending either at Wrestlemania or shortly after. He's appearing as a courtesy to his family after the roster became decimated by injuries.
This is not even counting the fact that Undertaker is already being advertised to appear on an upcoming tour for WWE.
Fantasy bookers are trying to connect a Sting run-in, but that would be so against his character to do that plus he is out with a probably career ending spinal stenosis injury.
I think we get an Undertaker clean win.
