I believe the other prevalent theory, proposed by Meso himself, is that, if this is a new Bionicle, then it would be the unofficial 14th year of Bionicle (10 years for G1 from 2001-2010, the story serials year 2011, and G2 from 2015-2016 for a total of 13 years).
Either way, I would, again, quell your passions on this one. I still hold that this isn't some insane April Fools joke for the same reason I didn't think the original was: Faber is a fan, just like us, and he knows the ringer the community has been put through. It would be cruel to tempt people with a joke like this, and especially so to plan it out as some year-long bamboozle. Along with that, April Fools just doesn't seem like Faber's thing, especially not the 900 IQ year-long fool.
14 could refer to anything. I suggest we wait until 2020 draws closer to see what it means.
