As of this past weekend, the latest word is that Sting has not yet signed an actual contract with WWE. Those within WWE continue to believe that the deal is very close to being finalized. Right now, it’s believed that Sting and WWE are working on the merchandising portion of the agreement.
The idea, which could obviously change between now and then, is that Sting will not be used at WrestleMania XXX in April, but likely will be used at WrestleMania 31 in California next year.
