Faber's caption with the image seems pretty relevant (emphasis mine):
The language used seems pretty certain (though maybe take with a grain of salt since it isn't Faber's first language).
It's starting to sound like #14B2020 is something confirmed and close to launch, rather than the ambition that it was originally teased as.
Which to me seems consistent with LEGO allowing Faber to build AFOL interest in a Summer 2020 Bionicle reboot. Hopefully they do it right this time and start some cryptic advertising through official channels when the new year starts.
