There have been rumors of a Nintendo Direct in January for quite some time now. The biggest bit of evidence came from a document from EA, which pointed to Fe being part of a Nintendo Direct presentation. While we haven't had anything officially confirmed since then, we did get a new tidbit today.
A member of the Resetera forum, who is apparently in the know on these situations, claims that we'll be checking out a Nintendo Direct on Jan. 11th. According to the forum-poster, plans were to run the Direct on Jan. 11th, and so far there haven't been any changes to the plan. If there is indeed a Direct, I guess we'll be finding out about it soon!
