Hmm some more data points about the PS4's selling out so quickly on Amazon. Apparently they supplied Amazon with 12,000 sometime last week and they sold out in 27 minutes. Anybody see any numbers about Xbone supply? Hopefully we'll see more data as time as goes on.

On a side note, if we use Major Nelson's selective statistical methods = "the PS4 is selling at a rate of 19,000,000 consoles per month."
