So the latest tweet from Bryan Singer confirms that Bishop and Warpath will be in Days Of Future Past. The video he posted shows the names of the X-Men characters although it seems to be those mainly from the original 3 movies - Wolverine, Xavier, Magneto, Storm, Colossus, Iceman, Kitty Pryde as well as the newbies Blink, Bishop and Proudstar. There’s a total of 12 seats though so looks like Rogue could be one of those?
I really can’t wait for this movie! ARGH. See the video clip here.
