Nothing is official until the summer convention in Tampa, but at the RNC state chairman's meeting this week, the party provisionally rejected efforts to make further changes to the primary calendar rules for 2016, thus largely keeping the 2012 calendar rules intact for now:
http://www.politico.com/news/stories/0412/75368.htmlSo we could very easily end up with a 2016 primary calendar that (at least on the Republican side) operates under very similar rules to the 2012 calendar, including the same dates on which states are allowed to vote without sanctions, the same rules on proportionality, and the same carve-out for IA, NH, SC, and NV.
