Here's a table showing the adjustments made to the numbers for the week ending 8 October and the Quarter 1 through 3 numbers. As far as I can see the Wii received no or tiny adjustments,the X360 has only seen adjustments for September and beyond based on NPD numbers. PS3 looks to have been adjusted for it's post-price cut numbers. 3DS has been been taken down 500k lifetime numbers, while DS has subsequently risen by 400k. For last week's numbers PS3 is up ~10k and ~20k in Americas and EMEAA, while 3DS is down ~20k and ~25k in Americas and EMEAA.
btw I've taken Media Create numbers to complete 15 October numbers.
