Re-cycled Mayan calendar nonsense

... or, B'ak'tun The Future. There's some buzz going around the web right now because some Mayan archaeologists found wall writings in the Xultun ruins in Guatemala dealing with the Mayan calendar. The writing clearly shows the Mayan calendar extending well past 2012. As you can imagine, this is being played up as (yet more) evidence the world won't end come December. Well, duh.
