Wrestlemania 27: What Would Your Main Event Be?

Everything is in the tittle really, I'm basically looking to find out what the most desired Wrestlemania main event is among the 'WWE Universe'. October/November is apparently the time where plans are put in place for developing the main storyline's heading into Wrestlemania.

It would appear at the moment that Randy Orton vs John Cena part 300 is going to be the main event but, this is the WWE plans change.

I would like your realistic hopes for the main event, when I say main event I do literally mean last match on the card. When I say realistic I mean nobody saying 'Edge vs Christian for the WWE championship in a Tables, ladders and chairs iron man match'.

Here are my top 3 matches that could main event in Atlanta early next year.

1) John Cena vs The Undertaker - my personal favorite.

I think this could be huge especially if Cena turned heel. It would be harsh on Randy Orton because I believe he deserves to be in the main event this year after the year he has had. Cena vs Taker is an instant classic for me and the added bonus that Cena is undefeated in singles matches at the showcase of the immortals. The storyline could be Cena wants Undertakers spot in the WWE as THE man.

2) Randy Orton vs John Cena - most likely at the moment

As with the match above this would be so much bigger if Cena has turned heel, I know we have seen these two face of an obscene amount of times but never in a one-on-one match at Wrestlemania. Also Orton is a babyface now therefore the physcoligy of the match would be different in a big way. This match always gets emotion out of the crowd which is exactly what you need in the main event. (Hope I didn't sound to much like Michael Cole there)

3) The Undertaker vs Triple H - The wild card

This has already happend at Wrestlemania I know but it will have been 10 years ago by the time WWE rolls up at the Georgia Dome. If you want a glimpse of what this match would be like see the elimination chamber match from 2009 when the last two men where taker and trips, they put on a mini classic imagine what they could do given a 30 minute slot going on last at mania. It doesn't take a rocket scientist to work out what the storyline could be for this one.

Would love to hear other suggestions
