they cant update you n00b. there is no code in the system menu to allow them to do so, despite you agreeing to them updating without your knowledge in the EULA. But they don't have the code, so you'd have to update for them to be able to update you automatically. If they just auto-updated you, they'd be putting themselves up in line for a lot of complaints, such as them wasting bandwidth without permission, and possible Wii bricking if someone unplugs their Wii when they don't know its updating. They can't yet, and probably never will, automatically update without your knowledge and permission.
