For now, only in Russian (thanks to Maiorboltach from RU community for posting it)
(Edit: fixed with English version)
In it (apart from video):
- at the time WG went out, models had 8000 polygons, more advaced models had 18k, but now, models will have 50k or so, with the most advanced ones over 100k
- there will be round roadwheels (no more octagonals)
- explanation of new shaders
- night maps, weather effects and thick smoke failed to make it to the game because of the FPS drop
- constantly snowing maps with reduced visibility (300 meters)
- dynamic weather (triggered by server, if for example snows 5 minutes in battle, reducing visibility)
