What ever the sales figures are - they're not good. EA recently estimated that X1 sales are around 30 million, but of course Microsoft made no comment on that estimate so it might be safe to assume it's either around that mark - or lower. Regardless, the Xbox One X didn't boost their momentum sales and it certainly wasn't received as well as the PS4 Pro, the One X didn't sell out on launch day nor did it sell out on Black Friday/Cyber Monday in the following weeks after it's launch last year.
On top of this, MS has an absolute dismal line up for appealing exclusives despite being on the market for 5 years now. It also begs the question: If people weren't excited for the Xbox One X, will people even be excited for Project Scarlet/Xbox Two?
