The reason for this lack of compatibility is that the headset requires a special driver to be present in order for it to function with a game. This explains why the upcoming Conduit 2 will work with the device, since the driver will presumably already be present on the game disc.
Games can theoretically be patched to include the driver, however. When pressed as to whether or not Nintendo or Capcom would be offering patches for games like Animal Crossing or Monster Hunter Tri, our contact stated that that information is not available "just yet".
Goldeneye isn't even supporting Wii Speak (that could change, but I don't expect it to).No there is NBA2K10,NHL2K10 and the Wiiware Uno game out now.The Grinder will support it too in the future as well.
So right now, this is the Conduit 2 headset. They're going to have trouble convincing people to buy it for just one game. The patching idea seems far-fetched on the Wii, which isn't set up for game patching. I can see the original Conduit possibly be patched for the headset, but I wouldn't hold my breath for Monster Hunter, and it's out of the question for Nintendo titles like Animal Crossing and Endless Ocean 1/2. (Whoa, did I just name every Wii Speak game?)

Don't forget Tetris Party Deluxe, that's another game which supports Wii Speak.
I'm not surprised by this at all. The Wii Speak is only a microphone, it has no speakers, and instead incoming voices come from the television's speakers. If this headset were only a microphone then it could work with Wii Speak-compatible games, or it could emit the entire game's audio, but it can't separate the voices from the main game audio.
