yeah i was just thinking the same as linkzmax, the "divertion" of consoles is an effect of low numbers and not a cause, since its available they dont need to send an extra 75k every week to stuff the retail channel, therefore they divert those consoles elsewhere.... now that I think of it, U.S. Wii has beat DS again this month. And Europe sales went up too...
115k US
90k Eu
30k japan
If you add those up you get the magic number of 235k units for this week (thats actually your average 230k week we have been having all year long)
And last week it was even higher
120k US
100k Eu
40k JP
thats 260k 10% above average, I guess it was because of Metroid Prime 3. But the thing is, even if in japan sales have slowed down, worldwide they havent.
