Your lifetime sales expectations for Xbox Series X|S?

[UnderwaterFunktown]

This is a hard one to predict because I have a feeling that Xbox are maybe going for a more fluid increase in power by making several "mid-gen" upgrades, so the "Xbox Series" as a whole might end up lasting longer than the regular console lifespan.

But if we assume that I'm completely wrong and that this'll just be a regular 7 year console then I would expect it sell around 60 million (though that might still include one or two models other than X and S released within that timeframe).
