TNA will not push or even mention Sting until he signs another contract. While there are several talents either out of contract or haven't signed one to start, there is fear that Sting could leave at any time and they don't want to have a situation to where they promote him and he disappears much similar to Shannon Moore. This would not be of concern to TNA if it were not for the rumors that Ric Flair wants to have his retirement match be with either Sting or Triple H but regardless if it's his last match or not, Flair is persistent in his desire to work one more time with Sting. WWE seems more willing now than in the past to entertain the idea of Sting working a lighter schedule. It is however believed that if Sting does come to WWE it's likely that it will require build up and some form of longevity after the match as WWE doesn't have a desire to have Sting come in for one match and then go away, similar to Warrior in WCW. It is rumored that Sting has singed a new deal with TNA though so that basically puts all that to rest.
