speculation.
perhaps, the production for Jap Wii was cut to increase Europe Wii.
Jap Wii were steady at 60k weekly for a long time and maybe they think the amount currently is good enough to keep a lead there.
Now, they are pumping out more units for Europe to take the lead there, too.
Why I think so? The Wii is dropping sharply in Japan to ~30k doesn't seem natural.
Ninty also said the #of Wiis produce per month is 1.8M/Month globally, so, increasing sales in any region will directly affect the others.
