Can we agree on an Xbox One acronym...

Serious business... :)

So... I see people are starting to use XBO which I can't say I'm a fan of. Can we come up with something better? Or do you like XBO? Contenders...
  • XBX1
  • XBXO
  • X1
  • XONE
  • XOne
  • XBO
  • Xbox
Votes and ideas please :)

Edit: Ok, so I've got a favourite now... (via Codiusprime).

XB1

It goes really well when you're writing about the next-gen! (i.e. PS4 & XB1)

Agree or disagree?
