Software should behave something like this:

420k-65k-35k-15k-8k-5k-2k

PS3 hw might do something like this:

35k-25k-15k-12k-9k

First day sales were higher than I expected looking at previous top preorder data vs. week one data.

MGS2 went from ~469k to 89k on a bigger userbase than PS3 has in week one to week two.

MGS3 went from ~498k to 115k on an even bigger base in week one to week two.

I'm thinking a disproportionately high number of the games sales will be day one, I wouldn't be surprised at all if it tops at 420k week one, even after a 300k opening simply because 420k is ~20% of the PS3 base in Japan.
