If Iwata resigns it won't be till after next fiscal year. However, I'm fairly confident with Nintendo's ability to turn it around. They need software to sell the console, a new Pikmin, 3D Mario, Mario Kart, Wind Waker remake for the later half of this year is nuts. On top of that there's The Wonderful 101 and the potential for titles like Yarn Yoshi and Bayonetta 2 to be fitted in somewhere. I'm also certain Nintendo will have at least 1 surprise title they haven't announced at E3.
The Pikmin games are brilliant, but realistically, I can't see a new Pikmin game selling tons of systems. Same with Wind Waker HD. You forgot to mention Monolithsoft's big RPG and RETRO's new title, if marketed well, I think they have a good chance at being system sellers.
