The black numbers are 3rd party sales on Wii, as you can see there's a ocean of shovelwere at the buttom of the barrel (plus some games that don't deserve to be there) but interesting to see that the number of 3rd party games that sold more than 100k on the Wii outsold the PS3 and 360 combined.
The PSP is a disaster, I can't see how to turn these numbers honestly, unless thounsands are getting their games on PSN now. PS2 seems to say goodbye
