What will be the year long build up to a match for next years Wrestlemaina?

Just thought it'll be good to get some speculation and predictions going on, before there is any indication on what the match will be.

From a background point of view, it makes sense for Brock and Rock, but wwe are not adverse to going with something out of left field, so I wouldnt be surprised if it was HHH VS Brock or something.

EDIT: I have just thought of something, DX vs Taker and Brock, Brock gets involved tonight to try and take out HHH for whatever reason but HBK stops him etc.

if they can persuade him then I reckon it will be HBK Vs Taker Vs Triple H for the long build up.
