Halo 5 WW > BO3 PS4 WW
Halo 5 will end at around 9 million assuming Halo 6 doesn't come out until until 2018. BO3 will end at around 7 million WW.
Both XB1 and PS4 sku's of BO3 combined will crush Halo 5.
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
