Yeah, I just posted this as well.. nice to think you have an original idea for 30 seconds...
This is what I assumed as well. Xbox Series X Elite and Xbox Series X Core or something, short: XSX Elite / XSX Core. Or perhaps completely different names with a 'Xbox Series X' label on the console box and on game boxes.I think Series X is just the name of the family of consoles they're launching. Wouldn't be surprised if the actual consoles themselves have very different names.
Xbox One X?
Lol.
