#4 The Undertaker is in action

Well, we already know that Undertaker is confirmed to appear, and we've already saw The Deadman in action twice this year - winning impressively over John Cena at WrestleMania and against Rusev in a Casket Match at the Greatest Royal Rumble - but could he wrestle on SmackDown Live?
It definitely has to be on the table. With Taker appearing at Raw 25 to cut a promo in his first appearance since Roman Reigns' win to seemingly retire the legend at WrestleMania 33, it looked all but over for The Deadman. Now we're looking ahead to the WWE Super Show-Down where Undertaker will take on Triple H for what's being billed as the final time.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
With Undertaker's role for SmackDown 1000 not yet defined, there's every chance we may see one more match - or even one final appearance alongside Kane if reports are to be believed that Jacobs will now solely focus on his political role as the Mayer of Knox County.
