An industry insider on ResetEra called Chrom has come forward revealing a few things he knows about future Nintendo Directs.
First, Chrom says that a Nintendo Direct that is shorter in length than the Nintendo Direct Mini on January 11 is scheduled to air on January 18, 2018. Chrom claims he does not know what the Direct will announce, other than there’s no particular game or theme to it.
Second, a larger Nintendo Direct will be broadcasted somewhere in February 2018. Again, no particular theme or game to this. As usual, take everything with a pinch of salt!
