*SPOILER* POSSIBLE SPOILER PREDICTION OF 2.21.11

So on the 3rd promo we can see someone dressed exactly like The Undertaker and standing inside the house and also we see someone walking towards the house wearing the same wrench coat. So I can assume that Sting and The Undertaker is coming back together.
As per my opinion the possible spoiler:
Undertaker was buried alive by Kane and Nexus. With the help of Sting, Undertaker came back from the grave.

Undertaker and Sting Together??

Many websites publishing it is Awesome Kong, and even some saying it is Shawn Michaels and Triple H. LOL.
Lets see what happens on 2.21.2011
