Overall there will likely be the two battle royals that we have come to expect on the card even though they aren't really that important. Knowing that the event will likely be between 6-8 hours in total with a two hour pre-show and a four hour main card likely planned I would hope that every time on the main roster will be included in the event in some form or fashion. At this point it is really to early to accurately predict many of the matches that could appear on the card.
With Rollins set to face either Brock or Daniel this will open up the possible opponents that could fight Daniel or Brock depending on who Seth selects. In my opinion I don't think that Brock & Seth will likely collide at the event as I think Seth will select Daniel Bryan; that leaves the Universal title and I think that Brock will fight Braun Strowman finally falling to the "Monster Among Men." Other then that it is tough to predict the direction that the company will go and I think that we will get a clearer picture of the event following Elimination Chamber. We are still early on the "Road to Wrestlemania" and will find our way when things become a little more clear.
