I know you may be just joking along with the "doomsayers" thing etc. But I still want to put an accent on this.
Everything started with Mayan Calendar and media shoved it in everyone's mouth like its a big deal. There are as many theories at least as many news channels there are.
These are just a few:
Mass Evolution - its an interesting theory and I kinda read and seen some prove to that, like nano-tech announcement in 2012, breakthrough in microprocessors technology that will allow CPUs to be at least 10x faster than they are now etc. The some scientists created a diagram of evolution since whatever age and it shows that humanity evolves exponentially, sort of jumps of evolution at specific times, so they predict that around 2012-2014 there will be another evolution jump unlike any other before.
While graph goes exponentially from left to right, from lowest to highest, at around that time range it just goes almost vertically. Don't ask me how they come up with it, there is a whole hour devoted to it. Theory still of course, nobody ever can prove or guarantee anything like that. Just an idea based on their research of how humanity progressed until now including some specific times when humanity jumped to a new evolution cycle.
Revelation of Hidden Scriptures - this one partially based on lost Nostradamus book that was found recently. It depicts of world receiving some sort of message or placed before the fact and choice that humanity makes will carry it's consequences. Could be global warming reaching the limits and if humanity doesn't switch to 'green' gasses world will burn or something. Ozone level holes, and all that .
World is gonna end - nah, not gonna happen this way. Not yet at least. Or maybe it will end the way we used to know it, but I don't see how it may happen in only 2 years. Unless of course some scientist Bob finds a way to break through the veil that keeps everything balanced in the world and creates a piece of antimatter in his kitchen.
Turbine releases Rohan expansion pack - now this is probably one of the most justified future events that we may see happened.
I can also add something like -
"Star Wars: The Old Republic" kills WoW .
Feel free to discuss/criticize add your own findings etc.
