Thanks for contacting us about Wii U; it's great to hear that you're looking forward to enjoying this console on launch day! Regarding your inquiry, while the bundles will only include a High Speed HDMI Cable, the console is compatible with the following cables:
Wii Component Video
Wii S-Video Stereo AV
These can be purchased separately and will offer additional hookup options. However, only one cable can be connected at a time; you will not see a secondary audio output on the back of Wii U.
