Also, in the original timeline, Scott's powers activated in '85 (or '79 as Set Harth suggests). Xavier was already bald when he recruited Jean as a child.
I try to look at what we've seen in both timelines and also think about what events would have occurred anyway with or without the timeline changing.
We've seen the stripe in Rogue's hair, which she got while in Magneto's mutant making machine in X1, in both timelines, suggesting that Magneto pulled of some variation of the same scheme in both timelines.
Likewise with Storm's white hair and Xavier's baldness, suggesting that both timelines had an attack by Apocalypse, which makes some sense in that I don't see how the changed timeline would have affected the actions of the ancient Apocalypse cult trying to bring him back.
With Stryker still in play, he could still potentially build his own Cerebro to kill all mutants as in X2.
The confrontation at Alcatraz in X3 may have still happened in one form or another if Warren Worthington II still creates his mutant cure (and I'm with the faction that doesn't believe the Angel in Apocalypse to have been Warren Worthington III. Wings could be a common mutation).
Yashida would still have sought out Wolverine in both time-lines upon his death, instigating the same chain of events from The Wolverine.
The only movie to be completely wiped away is XMO: Wolverine.
