So basically until another firm that actually properly tracks those regions does your job for you, we're stuck with an embarassingly incorrect figure on the front page. Go VGC.
I don't believe that are any firms tracking sales in those regions as they are so hard to track - certainly not on a weekly basis. The best we may get is a report from manufacturers as to how many units they have shipped to a region or some rough estimates from a local trade body or similar. I doubt if there is anyone in the world who could accurately tell you how many PS3s were sold in India last week.
Weekly PS3 figures in India? Funny, but what we're asking of you here is nowhere near that level of accuracy.
You have to wait on other people's numbers because you have no idea how to account for over half a million PS4s sold in the past 3/4 months.
It's fair to say that we expect you to have some broad idea of where that many units are allocated. That's a massive amount of the hardware market that until now you apparently didn't realize existed.
