BUt there weren't many of them on that map. There are Jerkbait Islands (probably NW), the Rock of Gelato (NE), Flotsam Island (SE), two unnamed sandy cays (SW) and a small island on the verge (NE). I think we can safely assume that episodes may take place on larger islands only. So, we have Flotsam and Jerbait Islands (which are so close that they'll probably be featured as one) and that's pretty much all. Unless Telltale wants to reuse islands between episodes, I believe there'll be some new ones (2 sets are simply not enough!)
