Apparently there had been some unhappiness among the WWE gamer community over the lack of Divas Revolution presence in the game. 2K Sports posted this statement in response:
"With our final roster reveal this past Monday, it was awesome seeing the excitement for The New Day, Enzo and Cass, Mikey Whipwreck, and more. But it was clear that some in the community are frustrated by the lack of the newer Divas added to the main WWE roster recently.
We pushed as hard as we could to include Sasha Banks, Charlotte, Becky Lynch, and Bayley in WWE 2K16, but it simply did not work out for various reasons. While we are not divulging full details on WWE 2K16's post-launch plans just yet, we can confirm that the Four Horsewomen will not be available as DLC.
We are proud to have and built the largest WWE roster to date featuring the most Divas ever. The WWE 2K16 disc includes all of the Divas on the main roster at the time we locked it in (13 playable in total).
We all agree the Divas Revolution is great for business and look forward to celebrating the Divas even more in future WWE 2K titles."
