Oof, its dangerous to doubt a Tbone thread and I don't think its completely impossible either, but in the crazy world where it did occur, I think the split between quarters would be different.
Even the DS never shipped over 12 mil in one quarter and they were probably better prepared for such a high volume of shipments back then, so 13,5 mil in the holiday quarter seems too far fetched for me. I think if this is to have any chance then Q2 and Q4 have to pull more weight, at least 6 mil each as crazy as that sounds.
