No asteroids in 2012, no stray planets, no comets, no solar flares, no coronal mass ejections, no gods appearing from the central American region.
No planets lining up, no line ups with the centre of the galaxy except for the ones that almost happen twice every year and it would not matter if there was.
The only great enlightenment that will happen is when 2012 believers realise they have been duped. Some of them might wise up and stop believing in the Bermuda triangle, black helicopters, chem trails. the Illuminati and all the rest of the conspiracy claptrap. But there's no guarantee of that.
To make a long story short, all the 2012 stuff is lies
