ORBX is really famous because of its TrueEarth products to X-Plane 11, for example, TrueEarth Great Britain, Washington or California. Now they are working on Florida, and some interesting previews have been shared.
Previews were made on ORBX forums by Iain Emms, and shows off the cityscape of Miami, and the surrounding area. Of course, the product is going to be big and will have so many accurately placed buildings and vegetation. Unfortunately, any further information about release has been not shared yet.
Further information can be found on the ORBX forums. On FSNews, we will inform you about any updates about the development.
