Wii's pretty low right now (Before DQIX of course).
I worked out the weekly average for the Wii since launch in Japan about 2 weeks ago or so and it came to over 60000 units.
Wii hasn't seen those levels there in a while, hopefully the situation will remedy itself soon.
At least the x360 is trying to do it's bit for the industry there as opposed to last year
