I moved the Vietnam events of Origins to 1979, because William Stryker is older than his DOFP appearance and is a Major, not a simple Lieutenant like in DOFP.
Anyway, I must confess I'm starting to think Origins is a third timeline, a standalone continuity, a "what if" story. 2016's X-Men: Apocalypse will tell. It depends on how they are gonna handle Cyclops, Marvel Girl, Gambit, Deadpool and Wolverine in future post-DOFP X-Men movies.
Stay tuned... I am here.
