I don't know if Nintendo is going to have much of anything for this fall and winter other than what's already announced. Brawl was shown at E3 06 and came out in Spring 08. Mario Galaxy was shown at E3 06 and came out winter 07. Zelda was being shown for like two years before it appeared in Winter 06. Super Paper Mario was I think E3 2005(I could be wrong here) and came out Spring 07. Mario Kart was shown at E3 07 as was Wii Fit and both are arriving around Summer. I don't see anything major Nintendo would announce that would show up by the end of the year.
I think a smaller franchise or two could show an appearance. I would give a large bet on Pikmin hitting, possibly Animal Crossing and an original IP(maybe by n-Space).
The Wii actually has a heavy hitter coming this Fall called Wii Music. This title may or may not be quality, that's still on the table, but I will put good money on this title selling like hotcakes. There's also Disaster: Day of Crisis which will satisfy the more action/adventure hungry bunch.
The thing is, the Wii has spread it's big titles out this year either on purpose(Mario Kart Wii and Wii Fit) or by happenstance(Super Smash Bros Brawl). I feel like this Fall will be a little thin on first-party offerings i'll like, but I'm hoping to be wrong.
