I don't agree with him that they need that "one" software title and Wii U will do blockbuster business. That seems like such an impossible goal. Pokemon was 20+ years ago, and they haven't created a new IP phenomenon like that since, so I wouldn't hold my breath for it now. What they do need to keep doing though is building their strong first party software lineup. MK8 helped sales a bit, Smash helped them even more. I think another 2-3 titles on that level and the Wii U would be in completely fine shape. Hopefully some combination or all of Zelda, Star Fox, Xenoblade, Splatoon, and Mario Maker does that for them by the end of this year.
Though back on the topic of that "one" title Iwata mentions...I have to hope there is some kind of new Amiibo focused IP in the works. That would be their best bet to create that killer IP for the system that could propel huge sales, with how well Amiibos have sold despite their relative useless-ness. An addicting and fun game centered around them could definitely be huge.
