Which buildings will be the tallest in the world after 2010?

Question

Ok so I have been reading about future and current buildings in the U.S and other parts of the world but I can't really catch which ones will rank in lets say the top 10 tallest building in the world. I know the Burj Dubai is currently the tallest...well when its completed in 2009. I also read something about the Chicago Spire which will be pretty tall too. Then comes the Freedom Tower. And the Sears Tower I believe is the current tallest building in the United States. Well anyway...can you give me like a list that consists of all the tallest buildings? Including these towers I just mentioned and other tall ones around the world. I don't just mean in 2010 or something but also buildings that are scheduled to be ready by 2012 or such. I would really love to know.

THANKS TO ANY HELP! =D

Answer 1

The buildings that will end up being the tallest are not yet under construction and there is no way to tell where they will be built.  You are right about the Sears Tower being the tallest in the U.S. right now, though.
