I don't get why you are against chinese market being accounted for on a global scale, even when AMD released 3 GPUs specifically for the chinese market (6750 GRE 10GB, 6750GRE 12GB and 7900GRE), some particular reason you would like to share?
First you say MS own the majority of game studio that will make games favor AMD, which is definitely not the case with the newly released Indiana Jones. Then you make reference to POE2, which is not owned by MS in any way and heavily favor RTX, kinda shooting yourself in the foot there. Thirdly it's quite absurd to even think North America has the majority of game studio in the world.
Edit: if you don't believe in Steam chart nor this Jon Peddie report, how about AMD own financial reports and their dwindling gaming sector revenue?
