I called this. Skipping the WM after the end of an era match gives off the impression (kayfabe wise) that he really is retired, only for him to come out and challenge Cena to one final match at Wrestlemania 30 (or vice versa) because Cena is the biggest challenge left for him to take on. It makes me fear though that Cena will beat the streak because at least then Undertaker can say he made to at least twenty wins before losing. If they become so desperate to make Cena their biggest star ever that they give him Taker's streak, I'm seriously done with WWE, which means I'm done with wrestling entirely. That sounds like a hyperbole statement, but I'm already nowhere near the passionate wrestling fan I used to be, this would be the thing that drove me away completely.
That said, it's good that the main event might be a triple threat (called that too, Cena's Raw promo hinted at it, me thinks) but I was hoping that would install hope that Taker/Brock would happen instead of HHH/Brock. Because I could still see Triple H sitting WM out before Undertaker. Guess not.
