The stretch goals are pretty sweet. The first is a SotDL update to the classic Freeport Trilogy. The Second is Beyond the World's Edge, a 32 page expansion that details strange and bizarre islands. The third is Tales of the Pirate Isles which contains three one session adventures. The final stretch goal is the Demon Lords Companion 2, which if it's in anything like the first, will be an amazing addition to any SotDL game.
Are you a player of Shadow of the Demon Lord and curious about the content? Here are some some pages from the companion (which are not final layout, but contain some nice crunchy bits).
