Maybe this is old news but it's still extremely important that all Wii U owners know this, according to an article I read (won't post the link cause outside links aren't allowed) your Wii U will update and there's nothing you can to do stop it (unless you disable it's Internet connection.
If ever a Priiloader type program was needed for Wii U it is definitely a priority I'd say.
Just a word of warning, if you ever notice your Wii U updating DO NOT TURN OFF OR UNPLUG IT, you will kill it if you do.
