Most seem set on the January idea, but I just wanted to point out to those of y'all still saying February/Mar h, you should remember going into 2019 we knew of a ton of releases before the year began. Yoshi, NSMBU, NMH, DaemonXMachina, LM3, MUA3, Three Houses, Town, and Pokemon were all known quantities, not to mention delayed titles like Metroid and Animal Crossing.
Going into 2020 we know of TMS, Animal Crossing, NMH, Bravely, and Xenoblade. We know of far less games by comparison, so a January direct would make a lot more sense this time even ignoring all the other contributing factors.
