I don't know what's going on, but the last few weeks of Mario Kart Wii have shown what is comparitively a drop to the ground in it's sales.
From 90k to 67k, then 54k, 41k and 23k.
Here is the graph showing America versus Europe.

Is it dwindling shipments? is the game once again becoming difficult to find? or has the demand for it very suddenly dropped for some reason.... Had the drop been just 1-2 weeks in a row I would have been almost certain it was either supply of the game, or if the Wii itself had dropped in that time then the game would be merely staying with the console, but as it is the console spiked 4 weeks ago (some tax thing) but the game didn't... and after dropping back down the console has this last week rebounded... but has not taken MKWii with it.
Does anyone know what's going on? IS it in low supply?
