So primarily for organizational purposes, I would like us all to come together to make a complete list of all of the Wii U titles that we think will be released, but have not been announced. I'll organize them into three categories: Almost Certainly Coming, Probably Coming, and Possibly Coming. However, this is not a wish list, nor do I want this to be a list of all of Nintendo's IPs. Please only make suggesstions for the list if you have reason to believe that they are coming, and please tell us why.
Almost Certainly Coming:
-Animal Crossing U
-Paper Mario U
-Metroid (30 Year Anniversary)
-Fatal Frame (localization outside of Japan)
I will update the OP as people post.
