The latest MC charts followed Dec 26th to Jan 1st (edit: I did state that inmy original post. I thought I didn't). Which means vol.3 did 19K in 2 days since it was released on the 29th. This leads me to believe that, like vol. 2, the majority of the sales, if not all, were pre-orders. And, unlike vol. 2, vol. 3 did not sell out immediately since both HMV and Amazon have in-stock (not the case with vol. 2 after a day or two of release)
