I think many are forgetting that Nintendo wanted to release SSBB earlier, but it was delayed and that's why it was so close to MK. Still wouldn't of helped the fall lineup, but I think Nintendo was expecting 3rd parties to have better offerings available.
Honestly though, it's all about new hardware sales for fall, and they knew they would have trouble meeting demand. They didn't need a strong fall lineup to move the hardware. They need it other parts of the year to keep demand up. It's not like they would of sold any more wiis if they had any better games in the fall.
Now that supply is meeting demand, it's going to be a little more important, although there is a decent catalog of good games it's not really a problem for new customers, especially as wii software has the most shelf space in most stores.
