Was just checking something on the Marvel Wiki and discovered that they'd relabeled Logan (and the characters who appeared in it) as an alternate timeline from the main X-Men movie series. The Wiki now says it takes place in Earth-17315 (as opposed to the original trilogy's universe of Earth-10005 and the Days of Future Past's altered timeline of Earth-TRN414, the latter being where we all assumed that Logan took place).
Since it's not a "TRN" number, that means that the new number is ostensibly a legitimate classification and the Wiki cites this article as the source.
I've been finding very hard to find more information on this. Anyone else know if this is legitimately canonical or not?
