Nintendo released what looks like a minor system update for the Wii U this week, and it's available to download now. Going by the patch notes, 3.0.1 U offers "further improvements to overall system stability and software compatibility."
We've downloaded the update and can't see any obvious changes. Maybe the Wii U just wanted to make itself heard over the clamor of a certain other box.
