Indeed, this week brings us three zeros, darth and michael-5 on the X360, and non-gravity for the PS3.
last year for the "original" numbers there were:
4 zeros for the Wii
10 for PS3 (4 in week2 alone)
8 for the X360 (an incredible 6 of them in week!)
5 for DS
4 for PSP
weirdly none of them in week 1, my guess is it's an unfortunate time for adjustments with week 1 being not long after the fiscal results for the quarter... so we can all predict relatively accurately for week 1 then be dashed by an adjustment to the past data before week 1 is up.
