There’s a leak coming from 4chan (yes, generally a bad source) that could be legit and Is related to a new Dawn of War RTS under development by RELIC Entertainment.

There are also leaked images about the new Maps and It seems a update version of the latest Essence Engine
There are also related threads on subreddit that could corroborate this leak. https://www.reddit.com/r/dawnofwar/comments/1idonzj/valrak_about_dow_4/
