I actually stopped by a local Cannondale dealer (not MY dealer, cuz I loathe going there) and they let me browse through their 2012 dealer book. In the book, I read that the new seatpost IS compatible with 2009-2011 Synapse models. So yippee!!! I got my answer, and this dealer sent out an email to his C'dale rep inquiring on price and availability of the seatpost. He will contact me on Monday.
