I haven't read any of the impact spoilers, but it is speculated that they may have given the belt to Sting to end their "biggest PPV of the year" on a high note pleasing to the fans, but that they may want to put the title back on Angle soon, since they still consider him the top star. I've also heard Sting has been talking about retiring after his contract is up, so maybe they are just honoring him one last time...
