If you agree with my other points, then you must agree with the Wii numbers, which is selling on par with the Wii U and has a similar number of supply on shelves. Also, you must remember that while we are entering a slow period of the year and retailers will be ordering less stock, supply is still a little bloated from the holidays. I also imagine Nintendo was trying their darnedest to reach their already lowered goal of 4M.
As for the PS3, I chose the same number as the 360 because when VGC did adjust numbers right after shipments and Nintendo's charts, Sony and MS were usually shown to have the same number in supply. Sometimes MS was shown to have more. 1.2M just seemed to be a good number between the 1-1.5M that I believe ioi said was usually on shelves. 3DS was close enough to 1M, so I decided to leave it as is.
I fail to see how the PS2 remained relatively flat YOY, given that everything else is declining. If I remember correctly, I believe the PS2 was still selling in some US stores in early FY2011. The PS2 definitely did not have that luxury in FY2012. I don't recall any announcements of it starting to sell in any new regions, either. Most of that happened in 2009/2010. So, it's pretty easy to see why the PS2 would be down at least 27% YOY.
