Re: FOX Shared Universe
the possibilities are endless, but for some reason I dont see Josh Tank connecting his movie to X3, lol. Either Fox.
In any case, Im sure the apocalyptic future of DOFP will be seen just in this movie, and not on the next possible OT sequel.
And taking into account Jeff interviews, it doesnt seem like X-Force will be set in that world either.
So DOFP will be more or less like a One-off story. With only the FC cast continuing those storylines, of course. Maybe in the 80's, or late 70's.
The OT possible sequel could be something totally different and unexpected. Maybe the apocalyptic future leading to a new reality with Apocalypse, as rumored/speculated.... that would be pretty epic, without doubt.
Next Big X-Men Crossover
* 2017- X-Men: Age of Apocalypse
Edit: Forget about 2017:
