Can u imagine Goldberg, lesnar, and undertaker in the ring together.

Only thing that's missing is I really wanted styles to enter the rumble. He deserves to main event wrestlemania and his best angle is one where he says he spent his entire career working to be the top guy, and they took it away when he made it by creating a paper championship. So he enters the Royal rumble with the goal of winning and retiring the universal championship. Main event turns into a complete clusterfuck because retiring the championship is not "best for business," but TNA and Japan wrestlers intervene on AJs behalf and it's all out warfare with the WWF guys. Could even throw in sting and Goldberg on the TNA side as disgruntled wcw guys (or in stings case also TNA).

Or does Goldberg win, reigns retains, Goldberg vs reigns at mania, cena vs taker (either title or non-title, taker wouldn't necessarily need to win the rumble to get a title shot).

The above two scenarios are by far the most likely. I don't think anyone outside of taker, Goldberg, or lesnar is going to win. We know that the champs going into wrestlemania are going to be reigns and either of styles/cena (unless we get Jericho vs Owens). Pretty much anyone outside of taker/Goldberg/lesnar paired against one of reigns/styles/cena is going to be a flop. I don't see them doing something like styles v. Orton or Wyatt.

If it's not one of taker/Goldberg/lesnar, it's likely a surprise entrant, with styles vs hbk being the most likely, and Joe or nakamura as possibilities.
