Nintendo has released a new firmware update for Wii that brings the system menu to 4.3U. As of now, the only thing known that it does is remove the Homebrew Channel. No idea on if any features were added or not, but I’ll keep you posted. Just do NOT update if you have the Homebrew Channel cause it will be removed.
UPDATE: Nintendo website confirms the new update is to remove piracy. Here’s what their website says…

Wii Menu 4.3
Because unauthorized channels or firmware may impair game play or the Wii console, updating to Wii Menu version 4.3 will check for and automatically remove such unauthorized files. In addition, there are some behind the scenes enhancements that do not affect any prominently-used features or menus but will improve system performance.
