I guess we won't know until 2012. I can only tell you to not worry about that now. Live while you still can! Anyway, I'm with Hikaru_Desu with that. People can predeict but they aren't God.
Please.. Don't believe in stuffs like that! Many have predicted the end of the world but nothing cam true.. Please don't believe them they are NOT Gods!!
Don't get upset by that, what matters is you reconcile..
