Re: Is orgins still apart of the timeline now?
There is no way in hell that they will invalidate The Last Stand after The Wolverine directly referenced it.
Anyone expecting otherwise needs to stop deluding themselves.
Singer has said that there will be continuity maintained, but that he's also going to be making some changes.
This means 'altered timeline', not 'alternate timeline', so, no, Origins: Wolverine and The Last Stand aren't going to be excised from having occurred even if you think that they ought to be.
