I think it's because last week only counted one day of sales for the XL. Makes this a very good launch in Europe, especially considering there was no software release to accompany the redesign.

For comparison, the week of the price drop last year was 76.5k in Europe. The following week was about 86k.

Yup, Europe usually has a 2-3 week increase effect rather than one. It's just a different market. NSMB 2 should explode in EU, I expect it to be a big seller especially in UK/France/Germany/Netherlands

It's because of "The Best" version that just came out. I don't know why Tales of Graces F didn't do better on VGC though. It ranked 35th on the Media Create chart.

The Wii got a shot of adrenaline to the heart with DQX, and boy did it need it.

Hopefully, it won't drop off again too steeply and Japan Wii software will get a lift from all those new console owners. (Assuming they're not too busy with DQX)

All the Wii really has left now is the cut to $99 and the holidays. (A few games should still be moderate hits, like Just Dance 4, Epic Mickey 2, and Skylanders Giants)

Only 3.7m left to the big 100 million, can it make it?

Wii did in fact have a nice week selling just shy of 90,000 and beating 360 for the week.  The Olympics also brought a nice week of sales to Mario and Sonic at the London Olympics, placing that game which came out last year back in the top 10 in sales for the week.  In fact, it was a really nice week all around for Nintendo, as games on their systems held 7 out of 10 slots in global software sales for week ending 8/4.

3DS in Europe just slightly above last week, as expected. Wonder whta number will pull next one, before NSMB2.
3DS in America, I have the feeling it is overtracked a little.
