I've considered Taker the real Mr. Wrestlemania since 2002 when he had a great match with Flair. At that point, he was 10-0 and I just considered him the best ever in WM history.
Wait, do you not think Cena/Taker will ever happen AT ALL? That's pretty interesting.
What? Wasn't it you whom I talked to about Taker/Cena never happening like, ever?
Oh well, I noticed Taker never fought any certain era of WWE at Wrestlemania. He missed Hogan (Golden Era), Bret (New Gen), Austin & Rock (Attitude), and Lesnar (Post War). And since it's been going on for 23 years this 2013, I refuse to believe it was all coincidence. I believe Vince avoided booking Taker vs the face of an era at WM, so I have no reason to believe Taker vs Cena (PG Era) will ever happen at Wrestlemania 30 or 31 or 32, or at any Wrestlemania really.
But, like I said above, if I'm ever proven wrong and Taker/Cena does happen (highly unlikely of course), I'm willing to put my apology statement as my sig for one month to admit my mistake.
Speaking about WM 18, it's interesting to note although Taker has never faced the face of WWE at WM, he did defeat the biggest face of NWA/WCW ever in Ric Flair (and would have defeated their second biggest face had Sting/Taker happened at WM).
