VGC estimates that the Xbox Series X|S sold through 17.1m by the end of September. Lifetime sales expectations?

Based on my reasoning here, and my running theory on PlayStation and Xbox totals, 40% of 175-185 million = 70-74 million for Xbox Series.

So I'll tick the 70-79.9 option in the poll, but I'm obviously expecting it to be at the lower end of that poll option's range.
