Wii is the Lowest Selling #1 Console in Japan Ever.*

[Max King of the Wild]

Ps4 will improve over Ps3 in Japan. That's a given.

It doesn't have a high price tag and the first must have game fore the Japanese wont have to wait 3 years for Final Fantasy (or KH which ever comes first), 3 years for RE7, 4 years for GT7 or 2 years for MGS5.
