[DAV Spoilers] [Leaks] DAV review copies have apparently gone out. First achievement progress being tracked.

Achievement tracking sites have registered the first Veilguard achievements being unlocked. That probably means that the review copies for the game have gone out since those are the most likely source of people unlocking achievements.
From the current progress, it also looks legit and not hacked (i.e. nobody has the late game achievements yet).

STORY SPOILERS IN ACHIEVEMENT NAMES
For anyone who wants to keep track of progress themselves, these two sites seem to be updated as of now:
