Metroid Other M: July
Galaxy 2: early September
Zelda: mid-November
Depending on which title gets the most information revealed at E3, one may release in July (MOM) Nintendo may steal the competitions E3 thunder by releasing a title in May so they can boast of its sales by E3 (MOM).
I get the feeling Zelda may be delayed though. March 2011 is looking like a possibility, but sales will suffer as a result. However, Nintendo usually has a tandem of titles selling to end the year, (Animal Crossing/Wii Music, Wii Sports Resort/Wii Fit Plus/New Super Mario Bros Wii) so this year won't be any different.
