Things have sure got interesting with Sting... It came out a few days ago that he was frustrated with TNA booking, saw Dixie Carter putting him in the HOF as a way to put him over the hill and said Slammiversary needed changes (he is in the main event every year with the same result). More importantly, he said he wanted to work a program with Undertaker that led up to a Wrestlemania match.
Heard them say on Sirius today that he and Sid were friends and he had told Sid that his contract expired around January and he was expecting HHH to call. If Sid is to be believed (and I think he probably is), Sting would also like to work with Fandango or The Shield (specifically Dean Ambrose). It sounds like there is interest now.
