The article is almost certainly fake/wrong. Nintendo announced the increase in Wii sales forecast towards the end of July, had they encountered any major component shortages that stopped them from ramping up production in June they wouldn’t have made this announcement. Plus you only have to look at the July sales figures to see that June production went up.
Looking at the sales figures for the year this is how I read Wii production.
December
Production levels around 225K per week (from scratch), plus around 40K in completion of semi finished goods/ wrist band replacements.
January
Production levels around 225K per week
February
Production level drop to around 192K per week, probably due to component shortages. Nintendo had underestimated demand so it’s quite possible they under ordered components (done months in advance).
March
Slow start due to continued component shortage at around 170K, but ramps up quickly once components become readily available again. Lots of semi finished goods waiting for components allows production levels to hit 275K by the end of the month.
April
Starts well due to inventory of semi finished goods, then drops back to around 220K
May
Normal month around 225K per week
June
Production increase to around 350K. This is about the figure they need to be making in order to reach the new sales target for the fiscal year (16.5M). Knowing Nintendo and how they like to underestimate rather then over estimate it’s quite likely that the production may have increase to 400 or 450K.
