Upcoming Death Toll

OK so you guys already know that Michael has to choose whether to save the love of his life (Sara) or his bro (Linc). So we know somebody is going to die! What you don't know is, by the end of the season, there will be not one but AT LEAST two deaths!! So, does Michael choose Lincoln or Sara? Maybe he chooses neither? And who else will die? We know some folks are coming back so will it be one of them or someone else? Hmm... inquiring minds wanna know *scratching head*
