VGC estimates that the Xbox One sold through 47.8m by May 30th. Lifetime sales expectations?

Depends on whether they really release an Xbox Series S along with the Series X and at 300$ as has been rumored.

If they do that I don't think the Xbone will have a ton of sales left in it after that and will at best hit 51-52 mil.
But if a Series S ends up being a few years down the line instead or somehow 400$, then I could see the Xbone getting quite close to 55 mil.
