Randy Orton is in St.Louis this weekend and there is a chance he'll show up at Survivor Series, reports F4wonline.com. Wrestling Observer Radio has also confirmed that plans are for Sting to show up during the broadcast. In addition to this, the radio show also revealed that a third big surprise is on WWE's agenda. However, WWE could still hold back on that third surprise. The feeling might be that Orton and Sting are enough for the show. Alternatively, the company could use all their big attractions, in a bid to make Survivor Series a showcase of why fans should be signed up to the WWE Network. Despite not publicly announcing Sting or Orton, WWE are making no effort to hide their being in St.Louis. The company wants the surprise to get out, to create a buzz for Survivor Series. It is of course possible that Orton is just in St.Louis by coincidence, as he does reside in the state of Missouri. This is the WWE and Vince McMahon is infamous for changing plans at the last minute, so any of the planned surprises could change. As to what the third surprise beyond Orton and Sting is, it could possibly be Roman Reigns. The Big Dog is just a few weeks away from returning to WWE, so maybe he's recovered quicker than anticipated. Daniel Bryan showing up would be an outside bet. As for rumours of CM Punk returning, that's unlikely. The WWE did just unleash a few lines of Punk merchandise on WWEShop, but that's not an indication of a new Punk deal being in place.
