China/Asia seems to be where a lot of the AAA GaaS on Mobile market is at. Fornite is huge but from the doc leaks had very little playerbase on mobile. PUBG, iirc is the leader, and basically gets most of its money in Asia.
While MW2 will be big, I think its a lot of the same unfortunately, not as revolutionary as MW19 and we'll see from their financials if they can get close to the pandemic peak where it felt like everyone was playing COD.
