Wii U Spring System Update coming next week
Additionally, users will now be able to transfer data between USB drives and install background-downloaded software while playing other games. Installed software also has the ability to automatically download and install updates, without requiring the user to run the software first. Furthermore, the Wii U will now continue to download and install software while the system is powered down. You'll also be able to hold "B" at start-up to boot directly into Wii mode, if you're into that sort of thing.
