I get your point. But with all due respect, the comparison is unfortunately off by a substantial magnitude: overall VR devices sold world wide in 2019: <6M (https://www.statista.com/statistics/671403/global-virtual-re...)
xbox sales alone are quite constantly at 50M per month (!!!)
Then it sounds like you're not really getting my point.
VR as is today is a new tech. The Quest 2 is a recent release, second model of a new lineup. Xbox 360 was released in 2005 so look at xbox sales in like, 2006 instead. Which… checks numbers, hey look, 4 million units.

VR seems to be one of these things that keep on being promising I suppose...
