Well, my first guess would've been Xbox One Pro, because of the surface pro, but seeing as Sony has kinda taken that name already... I'm still gonna go with XB1 Pro.

I have this discussion with a friend all the time, it's because it's easier to market and doesn't confuse people.

PS4 Neo, 'dafuq what's Neo? it's new? is it better or just a new model? huh' PS4 Pro 'Oh, right okay'
Morpheus ' I don't even...' 'PSVR 'Oh Like Gear VR and other things'

Seeing Scorpio people wouldn't know what it is, they need a name that people can easily figure out what it is and means.

It would make sense, and put it in the same catagory as the PS4 pro.

People would easily understand, its the alternative to that. Get marketing on point, that their "pro" is stronger/faster/harder (daft punk music), and they could sell that name for it.

Xbox One S...S

Wait, probably not the best idea :)

Xbox: The Only Console with Halo & HDR & 4k & Call of Duty & Assassin's Creed & Pacman

or Xbox TOCWHAE for short.

It sounds fine, but people can mix it up with the Elite bundles for the OG X1. It won't be Scorpio, of course. It will also have "Xbox One" in the name since they don't want people to think it is a successor. Maybe Xbox One S Elite if they aren't that imaginative. Maybe Xbox One 4K or they will go with a random letter like Xbox One X.

Yes, I guess it will be some random letter like "X" or "P". They already went with this route when calling their slim model simply as "S".

Xbox One Amateur

Xbox One Balanced Premium

XBOX 10

That would confuse people into thinking its a new gen.  (remember the "Wii" "WiiU" issue, of people getting things mixed up?)

You cant not have "Xbox One + name" in it imo.... unless MS really are planning to forget about the Xbox One, and start a new gen.

In which case, Xbox Two makes so much more sense than XBOX 10 does.
