I think the Xbox naming is all because the PlayStation came out before the Xbox and if Microsoft would have used a similar version-incrementing naming convention they would have always been one version behind Sony. Thus the second generation of the Xbox being the 360, which competed with the PS3: the 360 had a “3” in its name, so to a consumer’s mind they were comparable.

I agree that that's why they didn't do a simple XBox 2, but I have never in the past 20 years had the thought that 360 starts with 3, so it's the competitor to the PS3. But even with that reasonable limitation guiding their decision, going from OG to "360", "One", and then "Series" is a pretty huge failing to establish a consistent branding. And "Series" in general doesn't give a natural sounding way to refer to this generation as a whole.

Ah, that makes some degree of sense. They could have done degrees of rotation like skateboard tricks, but then I guess the Xbox One would have been Xbox 720 which sounds like it's a 720p console.
