Well overtracking the DS is not bad, as NPD`s estimates are usually very conservative.
So on the good side are: DS, PSP, PS3, PSP
On the bad side are: Wii, XBox 360.
That´s pretty good I think - only the 360 has a bigger error margin, for the Wii numbers 10k a week are just 10% remember! That is still good.
Edit: read Lombard´s post, he is correct. Vgchartz was undertracking the Wii by 20k a week. that is 20%. but I honestly think Ioi is conservative with the Wii numbers because he doesn´t want us to be called Nintendo fanboys... you know, that stupid rumor was there.
All in all it is still pretty spot on for the most consoles (again: overtracking is not as bad as it seems).
