I heard that there will be one opening in Michigan in a joint collab between Oakland University and Beaumont hospitals. The first class to be admitted is expected to begin in 2010. Here is an SDN article on it
Virginia Tech will be opening a second medical school (already has research ties with VCOM, an osteopathic school in Blacksburg) with an affiliate hospital chain in the New River Valley. The first class will begin in 2009 or 2010, if I remember correctly. I think the plan is to keep class sizes small (~50) and heavily emphasize research.
