I agree they stockpiled some of the systems so maybe it wont be as high as 100K, but before the production increase they were making apx. 70K a week.
I think the production is an extra 200K + a month World wide which would give japan roughly 15K - 20K extra per week.
Based on that I would say that it will remain around 85 - 90K per week from now on.
