I know many of you are confused with timeline but i explain you what it looks like in short...
(alternative image link - http://s22.postimg.org/s2404a6v3/XMENTIMELINE.png)
Wolverine meets with Young Xavier, Magneto, Mystique and Beast 31 years before X-Men Events in 2004. This alone prevents Everything.
1)Wolverine will have bone claws - Wolverine: Origins event is prevented.
2)Wolverine half-brother Victor Creed is ALIVE(Prevented X-Men)
3)Stryker is alive(prevented X-Men 2)
4)Because everything else was prevented and changed - X-Men 1, 2 and 3 never happens - Jean Grey and Cyclops are alive
5)Wolverine Japan - never happens
So yeah, Days of Future Past is going to change everything. 1 change can change everything.
Because in original timeline Victor Creed dies in X-Men 1(Sabretooth) and Stryker dies in X-Men 2. Now when we have Alternative timeline, this means X-Men 1 and X-Men 2 movie never happened, this means Victor Creed and Stryker are both alive in new future timeline.
What you think?
