Love him or hate him, Mike Rinella has first-hand experience at creating excellent area-impulse designs. He also has a history of providing ongoing support (ie: mini-scenarios, variants, and articles) for his games. I'm picking this as one to watch as the end of 2010 approaches.
The guy is a prick with open disdain for BGG and it's user. If you want that support you'll have to head on over to Consim World.
