Wrestlemania Guest Host, Who is it?

Tonight Vince McMahon is scheduled to reveal who the guest host will be. His hints have been quite vague. He is quoted as saying, the following.
- This man is the personification of that special moment , that extraordinary attraction. That's never been done before.
- This man will set a banner, set a record like no one else because no one has hosted an event in front of 75,000 people.
- There is only 1 man... 1 man capable of pulling off this endeavor.


The names that are being floated around are:

• Bob Barker
• Justin Bieber
• Ryan Seacrest
• Stone Cold Steve Austin
• The Rock
• Aaron Rodgers
• Shaq

Well, I can tell you with an almost certainty, that given the clues that Vince gave, 6 of those 8 don't have the qualifications of a guest host.
Bob Barker hosted the prices right for close to 30 years. To the best of my knowledge he never hosted anything anything outside of a live studio audience of over 2000 people.
Justin Bieber has legions of fans, but does he really have the capability to give the 75,000 that special moment?
Aaron Rodgers has played in front of over 75,000 and he can captivate the crowd like nobody else on that list. The problem is, this isn't a sporting event. This is a hosting event. This is WWE's BIGGEST show. Aaron Rodgers might be an A list quarterback and someone that everyone is sought after, but WWE needs someone that has charasma like no other.
Ryan Seacrest is in the same category as Bob Barker. He's hosted American Idol and been in front of thousands of people. But is he really the personification of that extraordinary attraction? I really don't think so.
That leaves 3 people. Shaq , Steve Austin and The Rock.
Shaq is a huge WWE fan. He has the ability to make people stand in awe when is in the ring. He did it back in 2009 and was in the ring with Big Show and Jericho. People were talking for months about a potential match up between Shaq and Show. Close to 18 months later. Nobody is talking. People have forgotten. Now would be a perfect time to reignite one of the best guest hosts RAW had.
Steve Austin is also the perfect guest host. The problem with Steve Austin is the fact that he gets WWE air time at least once a year. So fans aren't missing him like they are other former superstars. Would he be a great guest host that could give that special attraction, that never before scene moment... That would set Wrestlemania 27 apart from every other Wrestlemania? Yes, absolutely but not as well as the final man.
The Rock. The Rock hasn't been in a LIVE WWE ring in close to 6 years. He hasn't done anything regarding the WWE in close to 2 years. When he speaks , EVERYONE listens. He spoke on his facebook account a little over 2 weeks ago that his although his wrestling career is over, he is looking to do something in the WWE sooner then people think. Why would he post that unless he was hinting at something.
If I'm a bookie and I was to give odds on these celebrities, here is where I would put them:
Justin Bieber: 12-1
Bob Barker: 24-1
Aaron Rodgers: 50-1
Ryan Seacrest: 75-1
Shaq 20-1
Stone Cold Steve Austin 10-1
The Rock 5-1
