Bryan Singer has confirmed that X-Men: First Class 2 will revolve around the Days of Future Past comic run.

Singer exclusively told IGN that the script is being written now, adding ďItís going to be very ambitious. Itís called Days of Future Past and it deals with aspects of that comic but also some very new things but I donít want to give any of it away. Matthew Vaughan will be directing and Iím totally excited about it.Ē
