Well enough digging I found another answer

Note 5's update, which looked imminent before, as it was the only Samsung
phone scheduled for Q4 2015, has now been pushed for Q1 2016. Actually, all of Samsung's newer phones are now set for a Marshmallow-ed TouchWiz in the next quarter, while some golden oldies like the
Galaxy Alpha, and a bunch of Samsung
tablets, will remain for the
second quarter of 2016. Given that it's already mid-December, and there is no Android 6.0 hitting Note 5 handsets yet, the leaked schedule below might have some merit, after all.
Manufacturers usually start updating their most popular phones within three months of Google releasing the source code for its newest
Android version, so a Q1 schedule is nothing out of the ordinary for the
S6,
Note 5, and below. Unfortunately, the October outing of the Marshmallow source code also means that the new
A-series 2016 of Samsung wasn't prepped with Android 6.0 in mind, but hopefully Samsung will update them to Marshmallow soon after their launch.
