Once Japan comes online fullyband those developers start embracing the Wii U, Nintendo will have nothing to worry about. All those great Japanies games will be exclusive to Wii U beacuse of its bigger installed base.
Then once PS4 & 720 come out, their smaller installed base and high R&D costs will force developers to make games for Wii U as well.
I think Wii U will be OK.
