I might be a bit optimistic for PS4 this year since its been up YoY so many months. But last year had nothing going by the same logic. The top games were sports games and old games. This year we at least have Destiny 2 instead of Taken king or collection of Destiny. And LE bundles tend to just add to sales rather then replace sales.
Edit: Oh and 160k August last year became 191k this year. If we use the same % increase then we get 340k for PS4, but even I am not that optimistic. XB1 will definitely be down because it had a lot going for it last year and this year there is the XB1X.
PS4 had the slim model launch and a price drop to $299 in September 2016.
Won bet with t3mporary_126 - I correctly predicted that the Wii U's LTD at the end of 2014 would be closer to 9 million than 10 million. http://gamrconnect.vgchartz.com/post.php?id=6673287
