With the possibility of Halo landing in 2021, the price point of the S, and the assumption that Starfield gets announced as an XBox btand exclusive...I am going to go with a very optimistic 15-17.5 mil.

Xbox has never sold more than 13.8 million in a single year, VERY optimistic  to suggest 17.5 million

Well, there is always the possibility of a first. (-:

But yeah, too bold for me, I go a little lower.
