To continue from my earlier post about US numbers, the PS4 is at least 100k over tracked by Week ending Aug 02. From the same week ending, the Wii U is at least 96k over tracked.
PS4 100k could easily go to other other countries, but Wii U could still be under 7 million as of Aug 26, especially if they are over tracking US again for August.
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
