Nintendo is always a tough beast to deal with as I believe none of their major games have release dates outside of Metroid which technically is a summer game (based on the scale using) since releases at the end of this month.
So let's see what Wii has in store for this holiday season since there is no new peripheral.
Sept
NHL Slapshot

It has all the trades of a top selling Wii game. It comes with some accessory. It looks like it could appeal to a very unique crowd, we shall see.
Batman: The Brave and The Bold

Based off the hit cartoon, and well Batman is well known. Also made by WayForward who were responsible for Contra 4 and A Boy and His Blob
