New Wii U firmware update

There's a new firmware update available for the Wii U. The update is 593 MB and is supposed to improve overall system stability. Seems a bit big for just system stability stuff but we'll see. I'm downloading the update as I write this so I'll add any new info as it becomes available.

UPDATE: So the patch was for system stuff. Addressing things like load times and system lockups.

The 3DS also has a system update for "stability" which doesn't add anything noticeable. One thing to note, Nintendo is having one of their "Nintendo directs" tomorrow morning so these updates may have something more to them.
