Have I got this right? - The 2012 alignment with the plane of the galaxy is NOT and alignment of our solar system crossing the plane as it swings above and below. That crossing happened thousands of years ago and we're now 'above' it heading further away from the plane. The alignment is actually one where we get the sun aligned between us and the galactic center (happens normally twice a year?) at the moment of equinox (both together happens rarely). So the significance would be more of a spin field torsion kind of astrological thing at best, rather than any kind of conventional thing like tides on the galactic plane etc.
The only other conventional significance I can think of would be if the sun actually does have a dark companion star 'Nemesis' out there, the gentle tug of gravity from the relevant bodies on each other and the galactic center/plane may have nudged thes bodies over deep time into some sort of periodic arrangement that does coincide in some way with an alignment such as will occur in 2012, and that such alignment alters...something. Oort cloud, interstellar dust...navigation pathways for a lizard race from planet X...?
