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.

AW is going to end up over 10m on PS4 alone.  You think BO3 will heavily decline never mind grow?
