That's impossible and irrational. How would a sales spike like that go away totally in 1 week? Simply take a look at DQIX and the DS. I hope you were being sarcastic.
And you also don't seem to realize that there was a Holiday in Japan were consoles have historically gone up.
Edit: You can check in that graph you linked to me, if you make it start 1 week earlier, that the Wii jumped from 37k to 52k without any big releases during Obon last year.
In fact the Wii saw a smaller jump this year compared to last during Obon. It was obviously not WSR fault, but the Obon boost. I'm sure that by next week Wii will be below 40k, and the week after it will be below 30k.

Bets with Conegamer:
Pandora's Tower will have an opening week of less than 37k in Japan. (Won!)
Pandora's Tower will sell less than 100k lifetime in Japan.
Stakes: 1 week of avatar control for each one.
