UPDATE - It appears that listings for Metroid: Other M and The Legend of Zelda: Skyward Sword have also appeared.
The datamining continues and it's not just Zelda we're talking about. Now the snoopers have dug up an official listing for Super Mario Galaxy on the Wii U. Now keep in mind, this listing is very different from the Twilight Princess listing. This one seems to be tied to just a regular Wii release, via Wii U eShop rather than an HD remake.
