Officially announced by Activision and Tencent is the free-to-play online COD just for China. Micro-transactions pay for weapons, perks, skins etc and the game is set within the Modern Warfare universe.
Feel like your missing out on a COD game? Fear not, the second the trailer begins it's clearly largely made up of MW1, 2 and 3 maps which haven't even been reskinned to look a bit refreshed. That said, Activision should really open this up beyond China as it'd still likely make a mint.
