In 2014, Batista was supposed to win the WWE Championship from Randy Orton at WMXXX. The crowd's undying love and support of Daniel Bryan and their refusal to accept Big Dave in his place led to a massive change of plans that saw Bryan capturing the title instead.
In 2015, Roman Reigns was supposed to defeat Brock Lesnar to win the WWE Championship at WMXXXI, a victory that was to officially appoint him as the new face of the company. While the match itself wasn't changed unlike the year before, the original planned finish was; Instead of Reigns capturing the gold, it was Seth Rollins via MITB cash-in instead.
That brings us to this year. The main event for Fast Lane has been officially announced as a triple-threat match between Brock Lesnar, Roman Reigns... and Dean Ambrose. The winner gets a shot at HHH for the world title at Wrestlemania. Is Ambrose only there to shake things up and eat the pinfall (which would be the easiest assumption), or could they pull a huge swerve on us by having him actually win the match? Ambrose is the most over person on the roster if we're going solely by crowd reactions, and should they get cold feet on Reigns again, he'd be the best person to headline Wrestlemania against HHH. They already had a stand-off at the Rumble, and you have nearly all of the same history and bad blood with him and Hunter as you do with Reigns, so it'd be an easy story to tell.
