Just finished X-2 in my rewatch. so far I've determined:
>The 1986 scene from the novelization is non canon, seeing as it deals with Scott being in highschool still (while he was taken by Sabertooth from highschool in 1979 so it doesn't make sense)
>The 1988 scene from the novelization says Storm is 12 years old, however, the DoFP timeline website features a cameo of an adult storm in their entry for 1991, so it's highly possible this scene is also non-canon
>The Nightcrawler prequel comic still seems pretty concrete (the movie constantly reitirates Stryker set up his attempt to assassinate the president, as well as his time in the circus, which were the comics focal points)
>Xavier's scenes in the intro of First class, even though cut in between Erik's scenes in 1944, happen a bit later seeing as he states multiple times that he met Magneto when he was 17. Leading me to believe that the scenes may be early/mid 50s
>Even though the year pass between rogue kissing the boy at the start of the original X-Men isn't explicitly stated in the movie, it is stated that the kid was in a 3 week coma, so some time did pass between that scene and the next with the novelization being the only concrete source on the amount of time.
>Charles states that it's been almost 15 years since Logan lost his memory, placing the original X-Men at the latest around February 1994
in X-2, Stryker states that is has been 15 years since Logan's memory loss, loosely placing the movie in 94/95. Obviously, those dates are not the case seeing as the DoFP website places X3 in 2006. Is it possible that maybe in the X-Verse the 3 mile island incident occured 10 years after it occured in our universe? It kind of makes sense seeing as how the past portion of DoFP occurs in 1973 and only 6 years later the professor has gone bald? seems like a quick turnaround. but then again I guess that would also pull the vietnam war 10 years into the future as well to match the "6 years later" time card. It's just hard to accept that both characters mis-spoke, and the crew of the movies didn't catch such a glaring continuity error.
Also, I wish a future movie would touch on how Sabertooth went from siding with Stryker into being allies with Magneto. As well as Why Xavier trusted taking in Stryker's son after he had rescued everyone from the three mile island.
