I'm a pretty big supporter of Xbox (had every console they've so far released, heavy into Game Pass) and my god they need to get naming right. They should have called it the "Xbox 4" or something to make it simple.
Though, Microsoft is never one for making names simple.
Xbox naming is terrible but at least their target audience seems to know how to keep them apart. I don't think that can be said about Nintendo's audience, which since the Wii has always seemed not as dedicated to console gaming as their competitors' audience is. I've never heard of a die-hard Wii fan, at least, though with the Switch they made up a lot of ground.
So instead they chose three numbers behind the PlayStation, and 359 numbers behind its predecessor? Not sure I follow that reasoning. Not to mention they could just jump to the same number as PlayStation used, just like MS also skipped Windows 9.
That said all the jokes at the time likely helped make it clear to everyone that the Xbox One was the new model. And Series S/X is just two letters, nobody seems too confused by that.
They chose a naming system that's not based on sequential numbers to both differentiate themselves from SONY and also to avoid being one number behind. Nintendo is doing the same.
I can't decide if that's better or worse than Xbox. Xbox One isn't the original Xbox? And do I want Series S or X?
