Re: "Romeo & Juliet Return?": The Official Jean Grey/Cyclops Debate - Part 1
If they do "time travel" again, it'll be redundant and weaken the impact it has on DoFP. But, yeah, the altered future will likely tell us what happened/changed in the decades proceeding 1973 in a subtle way. I wouldn't be surprised if they make it a film that wraps up the entire series. Not to say there won't be sequels, prequels or spin-offs, but it seems like it'll be an end-all for what's already happened in the previous six films. Though there are many stories left to be told, even if all the loose strings are tied up.
And contracts have zero implications on how many films the actors will be in, it just means they're contractually obligated to do as many films as they signed on for. Simple.
