There are rumours Modern Warfare 2 Remasted may be coming at the same time, and sport only the solo campaign.
Might even be a bundle, like the Infinite Wafare / Modrn Warfare Remastered affair of 2016.
Honestly how many people buying the yearly CoD release were playing it for the campaign? Getting rid of it is a cost/time saving measure. Not one they'll pass along but hopefully they will realize they don't need to spend $20m for a successful game and start experimenting more.
Goddamnit I knew game developers where greedy but now they are getting lazy to?
