I can proudly say that I will never support Japanese and if xbox started to be made in Japan I wouldn't buy it.
Why are you so racist?. You do know a large amount of the electronics in your house will have either been made in Japan/South Korea/Taiwan right?.
Also, it seems that part of the issues (the texture streaming) isn't apparent / being shown in other reviews of the game.
I really don't think that higher AF is really worthy of a recommendation especially when we know that the other version (XB1) has missing POM effects as well as a lower resolution and framerate(25 vs 20 fps ~).
