More interesting is VG Chartz is reporting the XBox1 pre-orders are more than the PS4 pre-orders of this game...
While their chartz are drawn in crayons...I can see this being true.
COD is the XBox shooter, Battlefield has more PS3 players than XBox 360, and KZ is currently lighting up amazons US charts (its top 10 right now and has already sold out its bundle) and is being bundled in Europe.
I really dont think COD is going to do 'COD numbers' on ps4, it will do well, probably outsell the other two (though an upset wouldnt shock me), but not by its usual margin.
