Nah!
Dude's doing some weapons-grade opium. I saw that analysis too - bad mix of numerology, cult theology, and pick-em vocabulary from the dead Roman language. My recollection and refutation are as follows:
The Roman numbering system grew up out of some even older cultures, and was really clumsy. In the counting of the Jesuan religion, which was a fringe group of Judism within the Roman civilization during its late stages, the Jesuan year 2012 was written by this "expert" as "MDDXII." He then turned it into an acronym in the Roman language with the following expansion:
M Mortuit
D Dominus
D Dictum
X (no word, assumed to be a symbol of Jesus, the central figure of the Jesuan religion)
I Jesus
I Invictus
with the rough translation, "God has ordained that all will die for Jesus the Triumphant"
Problem is, the vocabulary and phrasing would cause any respectable Roman scholar to pop an artery laughing, and the number "2012" in Roman is really written "MMXII."
So, I doubt that Chankahal is going to be pulled into the "Great Ocean" of the Romans by some sea monster any time soon.
