Wrestlemania - When was the last time?

Sorry if this has been done before,but I was wondering if we've ever had a Wrestlemania with arguably the two main events being built entirely on promos?
This has recently been really annoying me,I'm hoping for both Rock/Cena and HHH/Undertaker to get physical with each other,but will they?

What are your thoughts on this?are the build ups good as they are or would you like to see more action?

Last year there was no physical action between Undertaker and HHH before mania i dont think.

Im sure there will be some physical action between rock and cena. Rock isnt going to be at Raw this week but the following week (last raw before mania) im sure somthing will happen

No,you're right there,there was no physical interaction last year either,which makes it a bit more stale for me...thank god for Shawn michaels,he's made the match interesting for me.

I would like to see The Rock and John Cena vs Triple H and The Undertaker in a TAG TEEEAM MATCH PLAYA!!!
