Adjustments, adjustments. Anyway, I have updated the OP with the new numbers from this week. I also think I will discontinue tracking around mid-Dec, as this will be when we know for certain what the outcome will be, regardless of the results of one or two more sales weeks.
Edit: Just so some won't have to look back at the OP - As of week ending Oct 29th - 8,778,992(PS3) - 7,242,745(360) = 1,536,247 or ~192K over the PS3 for the next 8 weeks
