Re: SPOILER ALERT: Anyone bothered by....
I personally believe he should only have Bone claws in 1973, it would be in continuity with the rest of the series which he seems to be following with non of the dead characters from X3 returning in DOFP.
In the future though I hope he has the metal claws again, seeing him go up against sentinels with bone claws just wouldnt be the same, and there would be plenty of explanations they could use for him getting them back.
