Wii U’s day-one update is actually around 1GB or so, not 5GB

There’s no question that the Wii U’s day-one update is big. Just not 5GB big, as initially thought.

The full download is closer to 1GB. As you can see in the image above, only .47GB of content was exchanged after progressing halfway (roughly) through the process.

There are reports floating around that you can download the day-one firmware in the background, much like other updates. That surely makes things easier. You just need to cancel the update when initially prompted following Wii U’s initial Internet connection setup.
