There are not that many places that have the ability to produce the high tech MEMS incorporated in the Wiimote. And half of them are working on apple projects now.
Even if there are places that produce MEMS, the quantity is like a few thousand a best in a month, so I don't see a way to increase the production unless the companies that can make 400 thousand a month find a way to increase that by 25% which would make it another 100 thousand.
