In Japan: With the exception of a short period in Xmas of its first year when supply dried up while Sony tried to get units to NA and Europe, the lowest the PS2 ever sold in a week up until late last year was 19,960 in November '04, late into its life. The PS3, on the other hand, appears to be taking up permanent residence below that level. It's undertracking the GC there as well, with similar weekly numbers.
