#1 The Undertaker - Won't Return

The Undertaker has not been on WWE television since his match at Crown Jewel, where he teamed up with Kane to take on Shawn Michaels and Triple H. Since that match, 'Taker has been a part of a few wrestling conventions and non-WWE interviews.
It looks highly unlikely that The Undertaker will wrestle at WrestleMania 35, or even make a surprise appearance, considering how there's been absolutely no build for his Wrestlemania 35 appearance.

One theory that was floated about recently is that 'Taker could interrupt Elias' musical performance, but, to me, that makes no sense as there's been no build to the feud. The Undertaker and Elias have not faced each other in the past, and will possibly not in the future as well.
