It's odd, the ubiquity of World War shooters over the past two generations ultimately drove people up the wall, but now there's some who are clambering for a next-gen one, irrespective of Wolfenstein.
I'm sure that a big next-gen WW2 FPS could be a hit - they dominated the PS2 era for a reason. But Activision seems too committed to the sci-fi angle on COD to pedal backwards now.
Maybe as an off-season release? Like do World At War 2 in July, with BLOPS3 in November?
Maybe Border|Lines started as WaW2? What if the border refers to North/South Korea, and the conflict taking place in the Korean war? Perhaps this is COD's angle to really strike it big in the Asian markets.
Maybe you play as a North Korean soldier. Maybe Kotick lost the CoD rights in a Secret Illuminati Poker game against the actor that plays Kim Jung Un.
