I don't think we will ever see the day where WWE goes this route, but it has some real possibilities. Heel Cena vs. Rock in a rematch? Cena vs. Orton, Cena vs. Sheamus, etc. Plus, it would put Punk in a situation where he chases the belt from a heel. It has merit but I don't think we will ever see WWE pull the trigger on Cena going heel....and I hope we never see Johnny Ace on TV ever again.
Did that Hulk Hogan situation where he claimed Northeast Wrestling was lying and he wasn't going to appear at their show ever get resolved?
Yes, he is appearing as scheduled. As I wrote initially, Hogan misunderstood someone's Twitter post to believe that NEW was advertising him as wrestling on the show. That never, ever, ever happened.
What does Rey Mysterio say to the kids when he talks to them on the way to the ring?
Honestly, I've never heard. I would assume it's something different for each of them.
Has WWE or TNA ever showed any interest in female Strikeforce star Ronda Rousey?
Not that I have heard and honestly, they couldn't legally because she's under contract to Strikeforce.
Is the WWE paying the celebrities for their time as Social Media Ambassadors? Or are they getting something else in return?
I would guess it's a payment as well as free promotion for their projects on WWE programming.
