I was just thinking about this and I noticed there's actually an IGN article for it.
It really sucks that the Wii doesn't have microphones and headsets! With online play, I love how on the 360 you just plug a headset into the controller, but that wouldn't work with Wii games that require the Nunchuck, and plugging it in there would be retarded anyway.
The Wii has built in Wi-Fi, and it has 2 USB ports on the back. Unfortunately for me I use both of those already, one's for the wired connection because I'm out of date and don't have a Wireless router, and the other plugs in the LED/cooling fan stand which helps keep it from overheating in long play sessions.
Any speculation on how they can add voice support to the Wii?
I still hate the friend code system. It should have totally had something similar to Xbox Live's frontend for communicating and setting up game matches.
[Edit]
I forgot to mention, Wii Remotes connect to the console via Bluetooth so there's no technical barrier for Nintendo to release a first party Bluetooth headset for online gaming needs.

Think about this.
Battalion Wars 2, Mario Strikers Charged, Medal of Honor Heroes 2, Super Smash Bros Brawl, and other future games for the Wii featuring online play, will currently LACK voice chat support. I am HOPING that Smash Bros was pushed back to February because they want to release a Bluetooth headset in the meantime.
I'd be wanting MOH:Heroes 2 for the 32 player online multiplayer, but it's going to bomb if you don't have voice chat. I would be happy to see that game delayed as long as possible so they'll come up with a solution.
Really though, I don't want to go online with my Wii at all if I can't communicate with my teammates and/or opponents.
I do find it ironic that I'm bringing this up since it has little bearing on me personally, as I only have one friend who owns a Wii. Everyone else has a 360.
