I don't know that you guys and gals want to try this. With bricking stories going around, I'd hate to have you follow this info and get a bricked system. With that said, apparently you can have the Wii U day-one update downloaded in the background while you enjoy other Wii U content. Simply by pressing cancel at first mention of the update, the system will then download and install the update in the background.
Can anyone confirm/deny this report? Is anyone willing to give it a shot?! Thanks to Paul for the heads up.
