I always like this one for some reason. Also I think that the DS is that close.

Nice, I want to believe that one too

I'm not really sure what that one is getting data from.... the Sega consoles and the PS1 are definately wrong on that platform totals page, and I don't understand the reason the current platforms are all slightly higher on that page than the weekly sales charts (perhaps it shows a combination of last shipped figures plus some recent sales figures)

EDIT:

Wait... the platform totals page is including some data from the week ending 25th August (USA & UK)... wheras the weekly chart is still showing the w/e 18th August figures until the other regions are in.
You can see which weeks are included if you look here: http://www.vgchartz.com/weekly/
