Re: Has the WWE or WHC ever entered the Rumble?
It's happened but never after they announced the winner gets a title shot at WrestleMania. They had Chavo Guerrero enter as ECW Champion one year but the ECW title isn't a "real" world title, so that doesn't count.
I actually wouldn't be surprised if they did it with Ziggler this year. There's a Last Man Standing match at the Royal Rumble, a perfect opportunity to cash in, and his entry number is presumably locked already, because he won the beat the clock challenge. I don't expect them to be this clever but it COULD happen this year. I wouldn't bet on it though.
Several fans have sent in word that following the main event match between Roman Reigns and Seth Rollins last night on WWE Raw, about 1/3rd of the fans in the building left.
