So all books are direct competitors with same public? All videos? All Cars? Smartphones and Consoles?
Well you are on the minority as usually the people who buy late on the gen aren't the same that buy on the start, usually due to cost. You can get X1 or PS4 by 199 on promotions and have a big library with a lot of good games costing 5-10 instead of 400+ consoles with few games and all costing 60.
Well I have Xbox One already, if i upgraded it would be to Xbox One X or PS4 Pro.
