i think the hysteria would be worse than y2k personally. even if it doesn't happen you know not only the movies, but the newscasts will be cashing in on this come around that time just to get review's. it will bring it to the attention of people who didn't already know about it, people going crazy at grocery stores buying water/canned goods. others going on rampages of murder, rape, theft, etc thinking if the world is going to end they can do whatever they want and not have to face the consequences. thats what i think. even if the world doesn't actually end on 12/21/12, the mere thought that it might will bring something similar to the "end"
