Have you looked at their tour schedule?
Wanna explain to me how they are going to make it to Chicago in 2010 when they will be in Australia until at least the 15th?
That only gives them two weeks to fly home (which takes a whole day from Australia) spend a little time with their families, do any album promotion and appearances they have to, before they start their US tour.
Asking them to get there in 2010 is unreasonable.
It will be January at the very earliest before they even CAN do it, but chances are, if you are patient and not expecting them to achieve superhuman things, you'll find out soon they WILL be there in early 2011.
