Humanity of course will be long gone by that time - not through anything dramatic like nuclear war, but just crapping in our own bed and refusing to do anything about it because of short-term financial interests and general stupidity. For humanity at least:

 Not with a bang but a whimper

PS. The next person who mentions the Maya , I swear I'll scream. They were pretty good mathematicians but like everybody else they knew nothing about the future. The only notable thing about 2012 is that it will come between 2011 and 2013.
