Batista and John Cena vs. King Booker and Finlay is officially the main event for Armageddon. However, at the 11/28 SmackDown tapings, Vince McMahon changed his mind on the Armageddon main event on four different occasions.
There were three different matches considered for the main event, which included Batista vs. King Booker for the title (the original plan), Batista vs. Booker vs. Finlay in a three-way match (which he ended up putting on television), and of course, Batista & Cena vs. King Booker & Finlay, which is the official main event.
Furthermore, Batista vs. Booker wasn’t nixed because of their Summerslam & Survivor Series matches not going over too well with the fans. It is believed that McMahon made the call to not go with the Batista/Booker match because he thought that Cena in a tag match would pull in a better buyrate than that particular title match would.
