So your excuse is that whenever the wii has a low sales week(like say last week) in NA,its supply constrained? and that the wii can magically sell 1mil a month in NA without major software pushing those sales!? in a falling economy mind you. You sir are delusional.
I get tired of saying this line over and over, but I will try it once again. Check any pair of weeks for Wii sales in the last few months. There is a high week, and a low week in every set. The reason for that is because of shipment fluctuation. The Wii is still sold out through-out the majority of the US. Supply constrained products are going to have sales dips when there is no supply. How do you explain the extremely predictable and stable pattern of a high week, and then a low week when not all high weeks have big software hits pushing them? I am far from delusional. You are not looking at the facts.
Please explain the following graph if the Wii is not currently supply constrained: http://vgchartz.com/hwcomps.php?cons1=Wii®1=America&cons2=®2=All&cons3=®3=All&start=39467&end=39579
