Unless there are a LOT of unpurchased 64GB Pros sitting around, I would guess that the initial run estimates of 1MM Pros being shipped was a little off. Either way, 400k in less than a month is pretty good considering how difficult it has been for people to get their hands on the 128GB model. Looks to me that MS should just axe the 64 as well as RT and concentrate on the 128 (or better) Pros.
