The earliest is late February, when SSBB sales spike should stop. This would stop until Wii Fit comes out in not-Japan.
Basically January will be the test month where Nintendo figures out its real demand levels. Nothing big for that month besides Christmas oversales. If it's still over 1.8 mil expect a massive production boost this year.
My gut says sales won't cool down much over February and we'll have an increase to at least 2.5 million/month after the fiscal year.
There is no such thing as a console war. This is the first step to game design.
