Wrestlemania Matches that almost happened

This was on WWE.com today.  Their Top 10 matches that were planned, but never happened.  I hadn't heard of a couple of them.

I've heard of all of them.  The Shaq-Show one in particular was weird because it was on the books for months and then just never went down.  People were kind of pissed about the Cena battle rap not happening, as he ended up doing a lame skit with cardboard cut-outs of Jay Z and others in the pregame show instead.  The feeling was that it might have helped Cena become a bigger star.  Thankfully he did OK.  

Also, on the subject of WWE awesomeness, I'll top yours with THIS:
