Don't get me wrong, I like Christian - but there are many more possibilities I'd prefer seeing. I'm sticking to my theory from the very beginning... Punk vs Taker, Rock (C) vs Cena II, Ryback vs Show, HHH vs Lesnar, and the WHC match.
As for the WHC, I can only pray that Del Rio doesn't headline Mania as the champ. That said, I firmly believe they put the strap on Del Rio, only as a transition champ for Ziggler to cash in on - the sooner the better. I've heard a lot of predictions that put Ziggler vs. Orton. I'd rather see Ziggler vs Miz for the WHC at Mania. Two young rising stars, big egos, good chemistry on the mic and in the ring - I think that could be special.
But I think the bigger question is, where do the remaining cards fall into place? In my scenario, Del Rio, Orton, Sheamus, The Shield, Y2J(?), Daniel Bryan, Kane, and many others are still floating around without a match. Obviously, they will deservedly get one, but I'm just not quite sure how it will pan out.
