So you're saying that the Wii didn't make the console market seem artificially larger in Japan and that the shrinking of the console market is attributed directly to the failures of the PS3?

I'm saying if the Wii made the console market artificially larger in Japan then that applies to the gaming industry as a whole.

Which it did? 7th gen console total sales are bigger than the 6th gen. 

You can say that the "rest of the world" came into play here, but in the major territories, growth was caused the Wii. And yet in Japan, console sales shrunk. What is the reason for this shrinking when in the rest of the world, the Wii caused a growth?
