As I mentioned in the Reigns vs. Ambrose vs. Lesnar thread, and as Coco brought up already, WWE runs a big risk in putting Roman Reigns over two guys at Fastlane who're much more popular than he is. Putting Roman Reigns in the main event at WrestleMania against Triple H may well have the exact opposite effect Vince hopes for in that they'll cheer Trips instead just to spite WWE management. As a result, I think simply declaring Roman Reigns the winner is premature and there's always the possibility of plans having been changed.
While there's been no word whatsoever, the match itself raises the possibility of Reigns' mega push being put off much later if not scrapped altogether because it hasn't been working quite the way Vince has hoped thus far. Since Reigns' big push was really started back in the fall, Raw's numbers weren't exactly through the roof and fans haven't wholeheartedly accepted Reigns. I'm not saying he hasn't improved and that he hasn't won over fans, but I don't see how it's possible Reigns has been embraced to the level Vince was hoping. During the Royal Rumble ppv, look at all the various wrestlers who ultimately eupstaged Roman Reigns to some degree: the hugely positive reception of Ambrose & Owens during their Last Man Standing match, Sasha Banks making her presence known & generating probably the 2nd biggest pop of the entire night, Chris Jericho lasting roughly 52 minutes in the RR match itself, the debut of AJ Styles & the buzz it created, Triple H getting a pretty generous reception when it was revealed he was #30, even though nearly everyone expected it, the big pop of the fans when Reigns was ultimately eliminated, the excitement when it looked like, for a few moments, when Dean Ambrose looked like he was about to eliminate Triple H. I mean, if Vince was hoping for Reigns to come off as this mega hero for fans to get behind, then his dreams were dashed.
