OK, I faced it: WiiU can't sell over 15M

[Turkish]

I'm betting on 18M as reported by Nintendo (no vgchart figure).

Wii U will end FY14 with ~10.50M total shipped
In FY15 it will have a price cut as a final push, sales will hover around 4-5M
FY16 will be the last meaningful year of sales, ~2.5-3M
