Well that list is definitely "realistic" enough to seem real. No talk of the major releases (Pokemon, Metroid, etc.) is definitely Nintendo-like. Taking it with a grain of salt though.
Pretty much if his "The announcement will be made on 1.9.2018 at 9 AM PT" doesn't come true then this rumor is false.
I can definitely see Nintendo holding back on announcing their big hitters (Animal Crossing, Smash, etc.) until the E3 Direct.
edit:
Calling fake after some thought and a quick look at some responses in the 4chan thread. Due to the "leak" missing at least one definite game that was supposed to be shown off in the January direct.
There is no mention at all of the EA game titled 'Fe', the game that had internal docs leaked which pretty much confirmed the January presentation..jpg)
