I agree with what's been said here.
There is no reason to keep the IOSU private anymore, Nintendo has already abandoned their WiiU and are focusing more on other profit-generating activities (NX, pokemon go...).
Nintendo has deceived us, players, with the low number of quality games we got for our 350 USD for a Wii U. So while Sony and Microsoft customers always get the best of the best (SFV, FF 15, Project Cars ...), the best thing we can expect from wiiu, is to see some indie game released here or there with 90s graphics...
