FWIW, the promo posters show Wolverine with adamantium claws in the present, and bone claws in the past.
Shouldn't it be the other way round?
Technically no, because the "past" in DOFP is before Weapon X, so no adamantium at all.
As of the end of The Wolverine
, Logan still has the adamantium skeleton but had his claws cut off, and he regrew bone ones.
