This rumor is now false as it has been 20 days since a Nintendo Direct mini/micro. (1/11/18-1/31/18) There would've been an announcement this Monday if there were to be a Nintendo Direct today.
(My thoughts): Hopefully we get a good direct SOON as we still have no information on 2018 confirmed games like Fire Emblem & Yoshi, or big third party games because with all the business praise Nintendo is getting there still seems to not be many big 3rd parties hopping on the Switch, or online features like browsers, YouTube, voicechat, or My Nintendo coins being compatible with Nintendo Switch... because right now I believe the Switch is still lacking in some departments nearly 1 year after launch.
"In a thread by reddit user Natzore, it was noted that the time between each Direct Mini and the subsequent “standard” Direct has never been more than 20 days. In instances where there were consecutive Direct Minis, the date was taken from the last one.
A table Natzore added to their post showing the time between the Minis and full Directs is below:
