Just a heads up for people who want to play their new console immediately and still update it.
Last night, I set mine up and hit “cancel” at the first mention of the update. We played Nintendoland for a while and then I went to update it. To my surprise, it skipped downloading and simply started installing it. It took less than 15 minutes.
The best part is that it only downloads it. If your power goes down then the download will simply stop. Your Wii U will not be bricked...but I guess it's a little bit too late now isn't it?
