First UFC champ to fall in 2012?

Here's an interesting question: which of the seven current UFC champions will lose their title first in 2012?

Will it be featherweight champion Jose Aldo Jr, who is first up to defend his title this year? (He fights Chad Mendes at UFC 143 in Rio on Saturday, Jan. 14). Or will it happen in Japan when Frankie Edgar defends against Ben Henderson next month? Or do we have to wait even longer for the next new champion?
