"We've got what we think is a great cast of popular favorites," says ABC head Paul Lee of the crop of competitors.

There is certainly a good mix of frontrunners and early exits (though should Johnson, Lachey, Smith and the other winners be able to add another trophy to their mantels?) in the mix.

Who are you rooting for? Are any of your favorites returning? Who's missing from the list?
