In my opinion, whatever happens..happens, and there isn't a damn thing any of us can do about it...OTHER than make the best of our lives today as if there IS no tomorrow and be appreciative for what we have now.
We have to keep in mind, too, that the entertainment industry, (American especially), take advantage of making revenues off of the most dramatic ideas...and as soon as the story of the 2012 "D" Day became a centerpoint of attention, the movie industry wasted no time to capitalize on the pubic's paranioa....resulting in spreading the fear only more.
You just have to ask yourself, what truly does hold meaning to YOU, and, again...attend to making your own life meaningful to the best of your abilities...whether that is until 2012 or....until much longer (as I suspect it will be).
(Also....We are bound to find what we seek most? Much like what "can" be found in the "Zeitgeist Theory". Seek, and ye shall find?)
I prefer to seek the good...therefore...All's good....
