One thing I'm wondering is what types of media will the Wii U support and be able to play? We're going to be able to hook up USB hard drives to it, which could open up a lot of possibilities. What types of music and video files will it be able to play? I have all of my DVDs ripped to a 2TB external hard drive that I'm going to be using with the Wii U. I would love to be able to play those movies through the Wii U. I would even be willing to convert all of the movies to a different file format that the Wii U supports.
I wish I knew what it will support so I can get to work starting on converting them if I need to.
