I doubt Nintendo would be so careless as to leave the prime fall season without a couple blockbuster games.
Also don't forget, Nintendo changed their policy to no longer announce games years prior to launch. They want to only make announcements about 6 months prior to launch.
I expect Pikmin, Animal Crossing (launch '09), Kirby, Mario Baseball, MP9, Disaster: Day of Crisis, Wii Music, and one or two surprise announcements - Kid Icaris possibly and/or a WiiFit type surprise.
