If you look at a lot of the weekly ads in the US there are a lot of 360 sales, so there's no doubt in my mind there's a price drop coming at E3 and/or there's a lot of stock. Maybe both?
I think anything over 1.0 million means It's undertracked here as there was already 85 days worth of supply on the shelves according to kowenicki's table.
It's just that simple.
