I would agree with DSPet and Virus. It is all speculation. Nintendo's description of the error code implies that a cheat code was detected while online. It would take a long time for Nintendo to try to "scan" every Wii for the HAXX ticket. The thing is Homebrew isn't even the program used to "cheat". There are many other ways to use codes other than apps through the Homebrew Channel. It doesn't make sense that they are trying to target Homebrew for this reason.
