if the gen last the same as the current one, easily 90 million and probably over 100 million LT about the same for PS4 + or - 10% LT depending on how Kinect and the media features are perceived down the line.... if it is a positive reception it will beat PS4 LT if not it will trail behind and lose a million a year over 10 years
now if a cloud based gen comes earlier because infrastructure allows it that could throw it off..... but I don't think we'll be there yet.... so I wouldn't be surprised if this gen last even longer unless a major improvement comes into light for the computer tech which is not the case so far....
