I personally feel that Rock vs Lesanr would only be a big deal among smarks and old fair weathered fans from the Ruthless Aggression and Attitude Eras (and even that is questionable). Plus, the match smells like Lesnar/Goldberg.
Don't get me wrong, you obviously influenced alot of people with your post due to the fact that Rock/Lesnar just took the lead in the poll, but I just feel that John Cena vs The Undertaker will have a more epic feel than any other possible match you can put on right now and that includes the "dream match" between CM Punk and Stone Cold Steve Austin (lol)
I am 100% sure that no matter what the outcome is for Cena/Taker, it will DEFINITELY change the landscape of the WWE. That's how big it is. I think most will realize it after the 2014 Royal Rumble when Vince will have to market his ass off for the 30th installment of this show. Hell, Mania 30 might be Vince's last hurrah with being extremely hands on with the company before slowly transitioning his power all to HHH and Stephanie.
I may be completely wrong but I have a hard time in believing that today's average wrestling fan (a kid or preteen who was drawn to the product likely due to John Cena) is clamoring for a match between two men who have not been around on a consistent basis since ten years ago. I think most of them would be okay with it, but not as emotionally invested like the would for a match between John Cena and The Undertaker. I even think most fans here would be more emotionally invested in a match between John Cena and The Undertaker.
Oh yeah, have any of you realized that ever since Cena became a perennial main event talent in 2005/2006, that he and The Undertaker almost never interact? Sure they had a six minute singles match on Raw that ended in a No Contest, and maybe two or three tag matches where they were both on the same team, maybe a different team twice. It makes me wonder if they are being very calculating right now. Taker having rematches at Mania makes me wonder even more if the plan has always been to have them face off towards the end of Taker's career, it's like he had this long series with DX at mania because Cena is the only threat left and they do not want to do the match yet. Because Taker is not done yet. Mania's 26, 27, and this year would have been a good time to do it. They are making us wait.
John Cena vs. Undertaker is a huge match. It truly is. You are not off base in saying that by any means. John Cena is the golden boy of WWE and Undertaker is the living legend that becomes more and more immortalized and worshiped with every Wrestlemania that passes. Cena would pose the biggest threat The Streak has ever seen, and that alone would absolutely draw.
I take nothing away from you making that point. But there is no way you can try and make the argument that it is bigger than a main event involving The Rock and Brock Lesnar. There is no WAY. The Rock is an A list movie star, and sure maybe some of the younger audience wasn't around during the Attitude Era to experience true "WWF Rock", but what they do know, is that he BEAT John Cena last year in the main event of Wrestlemania. He BEAT the top guy of today's WWE. Vince treats Rock as the mega star he is, and fans casual and hardcore alike know he's a huge deal. Really the bottom line with Rock is, he has moved ratings every single time he appears on any show, and is a proven draw...a proven draw for years. When Rock's on the show, he headlines, it's simple as that.
Brock Lesnar is the one that many of the younger audience may be not as familiar with. What they do know about him: he's a big ass dude who shows up ever few months for a big match, acts like a prick and then goes away. While the sample size of their perception of Lesnar in today's WWE is small, there is no question in their mind that he's an absolute beast and that he dominated the UFC - real
fighting. From a kayfabe stand point, they also know he "ended" Triple H's career which also pushes his star power a bit more within the WWE world. It doesn't take a lot to identify that Lesnar is no push over and is one bad dude. Lesnar is a well known name for, yes what he did in his first WWE run, but really for what he did in UFC. Lesnar has also proven to be a drawing power as he added a significant number of PPV buys to both Extreme Rules and Summerslam last year. Like I said, Lesnar is major investment (overpaid in my opinion) and I think Vince knows he has to put that investment in the spotlight. You don't pay a guy millions of dollars to wrestle in an under card match.
The national media know exactly who Rock and Lesnar are, and would treat a match featuring both of them like no other match up in modern history. That outside attention and promotion from the national media alone would pull in PPV buys that would out gross any match up featuring stars that don't really have a lot of pull outside of WWE.
You mention Cena being the main attraction for much of the WWE audience today, and that's why I said that the match can't JUST be Rock vs. Lesnar. Cena needs to be showcased as well, most likely going over both of those mega stars name.
Look, I've been a massive supporter of Taker since I started watching wrestling in the early 90s and have all the respect in the world for him and what drawing power he posses. But he just can not out draw Rock or Lesnar, let alone both in the same match. Taker and his Streak is the greatest and most coveted accomplishment in WWE, but it unfortunately is not bigger than a movie star and a proven pro athlete.
