3. Surprise Debut From NXT
WWE has been plan to call up some of the top stars from NXT, and one of them is the current NXT Champion Finn Balor.
It would be a shocker if he shows up as an entrant in the Rumble, but one should expect atleast one wrestler from NXT to show up during the Royal Rumble match. Bo Dallas & Rusev are the former NXT wrestlers who have been in the Royal Rumble match while still being a part of NXT.
