Re: 3 Reasons "Days Of Future Past" Is Actually X4
What I should have said was that another movie with the OT cast shouldn't be referred to as X4 (just as X-Men United was referred to as X2 or X-Men The Last Stand was referred to as X3). X4 would denote that it follows from X3, but it wouldn't, it would follow from DOFP (FC2 for FC and X4 for X3). So, if there is another movie with the OT cast, it'll probably take a second title, such as X-Men: Phalanx Covenant (God forbid), but technically, it would be X5.
