Raoul -Cloud gaming,This is already somewhat confirmed with them unveiling 2 consols, the mini having no disk drive. --- Although I guess it could still be running off the hard drive, Idk.
Anyways I'm excited to see what gets shown, had lots of fun with my 360.
My prediction- theres supposedly different controllers one thats been said to be rather flat and small, The always online will be for their cable/TVstreaming station that Microsoft bought and xboxmini. O and backwards compatibility with the 360.
