Didn't the XOne launch in fewer European countries? I'm not saying it would cause a massive boost in sales, but Xbox isn't in all the territories Sony and Nintendo are in.
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
