Yes, there's only four games that use this. Animal Crossing, NHL and NBA 2K10, and The Conduit. You also get a download code for the Wii Speak Channel. There are only three upcoming games that plan on using it; The Grinder (made by the developers of The Conduit), Endless Ocean 2 and Uno (WiiWare title).
It'll probably be just another of Nintendo's long line of accessory abandonment. Still a good deal though.
