I didn't VTC, but I would.
From the original question:
If we assume that the post-credit scene is in the Days of Future Past timeline, then we are left to explain why no mutants have are being hunted by Sentinels already.
I'll rephrase this for you: if the post-credit scene after The Wolverine is in the same timeline/continuity as the original X-Men movies, why is there no indication of the existence of Sentinels hunting mutants?
The answer to the question (which is not accepted, but not necessarily wrong) mentions that the Sentinels were planned to appear, but were ultimately cut (or arguably reduced to a head in the Danger Room).
IMO, the question has not been answered satisfactorily, but the question is a dupe.
