Drivatar is a ridiculous name, but the tech seems like a neat idea, even if they keep denying it's "AI" for some reason.
Also, Minecraft being there is neat, but it's hard to be excited for it when you know it'll just be a neutered (or at best the same) version as the PC, while also pulling resources away from the PC development.
As someone without much interest in MSGV, this conference has been a total bummer. Nothing they've shown has come close to making me interested in getting a XBone at launch.
Sunset Overdrive came the closest, but I need to know a lot more about it.
