... I think that the Apocalypse story will take place with the 1970s X-Men. I think the older crew is finished. They can still have Wolverine, and they can have Jennifer Lawrence and James McAvoy and all the new stars, plus some new X-Men if they want to add to it as Xavier forms a new team. I think that something about what Logan did in the past awakened Apocalypse, and now the younger team will have to deal with him when they're not ready.
The problem with that, of course, is that we now know that Xavier, Beast, and Wolverine survive into 2014. But I can't think that they'll use Stewart and McKellen again. I think they have to be done now, which means they can't keep going with the future story.
I agree that the movie was quite good. It's probably my favorite of the X-Men movies, and I love that they undid the horrible X3. Completely undid it. That's worth losing the events of the first two movies. Days of Future Past really put a bow on the last 15 years of X-Men movies, and now they can move forward. Almost certainly with the younger version, I have to believe.
Yes, we know they survive in 2023. I have to even wonder if Wolverine has any adamantium in his system since the real Stryker may not have gotten him. I think they will use them all somehow. They are just too huge to not use in some form. But I do agree that First Class actors will be the focus of the Apocalypse film.
