Wii restock invades Halo 3, Xbox 360 at retailer

[NJ5]

I don't understand this article. What's different about this week? Isn't it normal for the Wii to be regularly restocked and sold out at Amazon?

Whenever I check, I always see the Wii on the top positions of the sales ranking, even though it's usually sold out, so I really don't see anything special about this week.
