LOL seriously? Didn't both the DS and the Wii come out during Iwata's tenure? The Wii U will have to bomb miserably to counterbalance those--and 4 months in is a little short to be predicting that.
By that standard, the PS3 should've been a complete and utter failure based on it's first 2 quarters.
