That glowing blue light on the front of your Wii can mean only one of about five things. Well, this time it means there's another firmware update. In the absence of official release notes, all we have is educated speculation about v4.1 - but it appears that it only fixes a very minor issue with the forthcoming Wii Sports Resort where playing a game off an SD card would force you to rewatch the Wii MotionPlus tutorial. You can also guess that it might also block homebrew, though that's not confirmed either...
