Yes, that is primarily what I'm referring to. Not that it really bothered me that much in the X-Men franchise, but I'd really hate to see even more of the same continuity errors that plagued the PT-OT relationship extended into the ST as well. (Granted, Vaughn may not have been responsible for those continuity issues, and, as you say, X3 may be shortly retconned [we can only hope and pray]. My primary problem with Vaughn stems from Stardust; I genuinely enjoyed X-Men: First Class.)
