Nintendo has release system update version 4.2 for the Wii and it seems it’s purpose is to do nothing more than cripple homebrewed systems.  The update will remove the homebrew channel, as well as the most important couple of cIOS’ most homebrewed Wiis might have installed.  The guys over at WiiHacks are already talking about some quick fixes for those that accidentally upgraded their already hacked systems to 4.2, but buyers of new systems with the 4.2 update already installed may have to wait a short while before hacking up their new toy.
