To be fair, the VGC numbers are just USA, and not Canadian numbers, of which, VGC tracks as well.

For Canada, add around 10% for each system. That'd put the PS3 a bit higher (around 145k), and PSP @ 165k. Not perfect and off, but still closer than your assuming.

To add to that, you have to remember also how small ioi's data sample is at the moment. If there is a spike in sales at the stores he collects data from, it will favor certain consoles (in this case, PSP/PS3).
