The lights are on
The Wii U's second system update is available to download right now. Nintendo is being vague about what the update changes or fixes saying that the update offers, "Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience."
Nintendo also warns repeatedly not to unplug your system during the update as it could cause damage, and that it may take an hour to download the latest update. You should turn on your PlayStation 3 (it probably needs a system update) and your Wii U and make them race!
