Re: X-Men: Part 6 should be set...
I think they will jump the timeline to the 80's and do a Young X-Men trilogy, the sort of teeny bopper years of the roster. I don't think it is feasible to do an Avengers scaled movie like DoFP every three years without having the roof cave in on you at some point. The draw back being, a third FC movie (or a retconned trilogy) without featuring the cast from the OT would be a serious letdown for audiences expecting something bigger and bolder after DoFP. I think you see how it plays out. If you have a billion dollar movie, then I would seriously consider scrapping FC 3 for X4 AND X5. Again, it has to be for two pictures to justify the investment.
