Prediction: Wii U will sell under 40 million units

[Aerys]

It's too late, they had their chance, they didnt take it, nowmicrosoft and sony released their next gen, and sadly even the xbox one will sell better. ( and please, stop with that insanity of comparing Wii U to 3DS, the situation is absolutely not the same :

 

-3DS had good third party support before the Vita release, the exact opposite of the Wii U.

- 3ds is not a home console

- none nintendo home console sold well without first party support, even with mario kart, SSB,...)

 

So yes , 30M is the goal to reach now, what nintendo can hope ( and it will be very difficult if they cant even make 2M in one year, there will be a second price drop like the gamecube, for sure )
