Sting has yet to officially sign with WWE
On the Sting/WWE deal, WWE sent Sting his contract several days ago, but as of yesterday, he had not returned it. The belief is they were on terms and an agreement is in place, but as of yesterday, pen to paper on Sting’s side hadn’t been returned. There is no indication of any serious hold-up at least from the WWE side. Those in the company even before WrestleMania were working with the impression he was on board.
