So far we have...
Xbox - 2001
Xbox 360 - 2005
Xbox One - 2013
Xbox One X - 2017
Microsoft has a pretty unconventional naming scheme going on. For them, I guess it is "whatever sounds cool at the moment". Technically, they would have to call it Xbox Four, though. But then again...Windows 10 did come after 8.1, for some reason. Just call it
XboxV
They should call it "Xbox i" because "Games are so complex right now"
Xbox X5 sounds alright. Short and punchy to say and as a logo, static or animated would be nice. 5th major Xbox. #X5 #XBX5
They should call it X Box Zero to stick with the tradition
You have the Xbox
Then the Xbox 360, which means you went in a circle but still didn't go anywhere
Then the Xbox One, like step one, your starting point, still haven't gone anywhere yet
Then Xbox Zero, still at the same place
unconventional but not random, they pretty much all have some interesting explanation or idea behind, going with just a 5 wouldn't really suit their naming schemes history I don't think, also it's clearly not their 5th gen of consoles but 4th, also not even their 5th revision or spec if you are going to count the X you should probably count the S for example.
Someone probably still has that gif somewhereThey call it Xbox 360 because you turn 360 degrees and walk away
