The Game Gate VU is an arcade cabinet that houses an Xbox 360 or PlayStation 3 - a coin-op kiosk, more or less, with some other features. It's now been outfitted for Kinect. Anybody seen one of these yet?
BMI Gaming, a heavyweight distributor of arcade machines, lists the unit for $4,875 - with a $10 per month licensing fee unless someone's buying it as a free-play machine. Multiple units can be connected via LAN for multiplayer gaming.
Extravagant, sure. Maybe not the kind of thing you'd find down at your local arcade, should one still exist. I could see this sort of thing in Vegas, though.
