Next Trek Film : Two Part Movie ?

Trek script writers and producers seem to indicate that the next Trek movie will end with a cliff-hanger. Thus the third new Trek film will resolve unfinished business from the second new Trek movie. So essentially this means we are getting a two parter! Better yet this might mean they are going to film both films back-to-back. Thus this means we might not have to wait two years between the two films. So in theory the second film will be out in 2011 and then film number three in 2012.
