You’ve got to be quite the gamer to understand the hierarchy of XBOX consoles.
I have the feeling Microsoft intentionally sought to create this confusion so they can move the old stock as well. Example: Young Billy wants an Xbox for Christmas so clueless parents/grandparents go to Walmart and purchase something made by Microsoft with Xbox written on the box, preferably on sale and at a cheaper price.
Meanwhile Sony's over here with PS1, PS2, PS3, PS4, PS5, and all the sub-versions make perfect sense (base, slim, pro, etc).
