I just find this decision so bizarre if true. So you launch Modern Warfare 1 Remastered with Multiplayer, and by all accounts it was successful, but somehow MW2 doesn't deserve the same treatment? What the fuck?
Honestly if I had to put money on it.
MW4 is the 2019 game,
however i'd go so far as to say MW2's MP will be the basis of MW4 with OMA out and Chopper Gunner and Nukes more balanced.
Probably even a couple classic maps in there to further connect to MW2(Highrise, Terminal, Sub Base, Favela, Estate)
No need to saturate that market so they did the campaign to get people hyped and lead up to 4 which would basically have the MP and more.
It also would have filled the lack of a BO campaign.
