Zelda probably will come out this year. twilight princess was only delayed so it could be a wii launch title. wind waker was released 2 1/2 years of MM and they were working on completely new hardware. seeing how the wii is the GC.5 the've practically been working with the hardware for a decade. if it gets delayed its only so they they have something to release in 2011.
other games will be:
dragon quest X
Wii something?(possibly new peripheral)
pikmin 3
Kirby
unnanounced retro game
I dont think they'll be too worried about releasing AAA titles. I think they're shifting focus towards next console nov 2012.
