Sorry guys, but you are all underinformed. Everything what you can see in those videos are already possible under DCSW too, for 4-5 years . Blending grass, detailed trees (even with animated branches and leaves) lights, visible seabed, underwater ruins/wrecks, waves, reflecting buildings, dense city and road lights etc. Those are new objects only what were made by Dimitry Robustov who is the Terrain Programmer and Developer and by his Team in Minsk, subsidiary office of Eagle Dynamics.
Of course they made independent, individul and ordered terrains for private use of real simulator training centers such as Concorde XXI, Avia and for many other firms of the world.
