According to assorted prophets the 4th seal has already been opened with Obama being Anti-Christ, of course. Three more to go.
The next apocalypse is scheduled for 2012.
Not even that. Even if 2012 fails, each subsequent year till 2020 will have at least one, but usually 2 to 3 'ends of the world'. Can't wait to see them. So far, I've been through the assorted apocalypses of 1997, 1999, 2000, 2001, 2004, 2007, 2008.
