Just for funsies here's a quick estimate on how much the WiiU stock should be in the rest of the world assuming that it's based solely on weekly sales in any given region:
If we take the weekly sales from the week of the sales estimate and the three weeks prior we see that the ratio between Japan sales and worldwide sales is pretty consistent.
The average of the ratio for those three weeks is a ratio of .139 with a standard deviation of .013
Assuming all things equal then the shipments to consumer sales difference worldwide should be 1/.139 or 7.2 times that of the Japan stock
If the Japan stock is 40k as some have mentioned here and that's accurate then the worldwide stock should be 288,000. Therefore I'd guess the WiiU is about 200,000 overtracked.
Edit: and of course I did the month of July by mistake instead of June. At some point I'll have to check to see if the ratio for Japan to Worldwide sales in June was notably different from the ratio in July which I calculated here. That said, given how little the ratio fluctuated in July I'm pretty comfortable with the 200,000 overtracked estimate being close regardless.
Double Edit: Correct ratio from the four comparable weeks in June is 7.35 instead of 7.2 so I'm sticking with 200,000 overtracked.
