Microsoft/Asobo released this video yesterday, showing off some locations around the Pacific Ocean region. Some of the shallow water features shown in the video aren't yet incorporated in the sim, so it is a bit of a tease of what's to come with the future free updates. According to the Asobo devs, the extended shallow water and coral reef features that show up in Bing are being hand-edited before introducing them into the sim one at a time. Some such features did make it into the release, however, such as around the Turks and Caicos Islands and around The Bahamas.
