#2 Daniel Bryan's career-altering announcement
The most recent storyline on this list dropped without any explanation, this mystery surrounds Daniel Bryan, and only too place a few months ago. After the loss of the Smackdown Tag Team Championships by Bryan and Rowan to New Day at Extreme Rules, the eco-warrior promised a career-altering announcement that would change his future.
In the run-up to SmackDown, fans wondered what could Bryan's announcement be, and the show was sold by the WWE around the idea. Some fans even feared the worst, that Bryan would be forced to step away from the ring once again, just like he did in 2016.
By the time the blue brand aired, fans were itching to see what would it be, though Bryan instead came out three times during the night, but left without ever giving even a clue to what his announcement was going to be.
Instead, the former WWE Champion randomly wrestled a match afterwards with zero references or explanation regarding his decision. WWE reportedly dropped it to start Bryan’s new feud with Roman Reigns, but we’ll never know what his announcement was supposed to be.
