Well we can estimate the following for already announced titles:
May: Super Mario Galaxy 2
June: Sin and Punishment 2
July: ---
August: Metroid: Other M
September: Wii Relax
October: ---
November: The Legend of Zelda: Wii, Wii Party
December: ---
Xenoblade and/or The Last Story might be able to fit in there too if they come to the West. We know of Pikmin 3, Zelda Wii and Wii Relax (or whatever the VS will be bundled with) but have they all been announced? Wii Relax certainly hasn't been so that's one unannounced title for Wii this year, Zelda Wii we know is coming so I'd fathom a guess and say that Iwata wasn't alluding to that. Pikmin 3 has also been announced by Miyamoto.
I know that Retro's next title will be announced at E3, quite sure about that one. I doubt it'll make it out in 2010 though.. I guess the other game will just be a surprise!
