In grey goo, if you played it, you might've been the few people to notice the back story of the goo and what happened when we turned it off... So if you don't, or aren't 100% then tune in (yes it obviously relates to dreadnought, spoiler?) So, the goo were created to become a von Neumann probe (not liquid, not solid, von Neumann) and travel to the stars through some sci-fi reason, and every planet we got to that was inhabitable, we fought over. Eventually we smartened up after 9 (technically 8, the war stopped before ecosystem 9 was discovered, I assume) habitable planets "but every one, we fought over, in the end heard no new voices, no songs, no poems, only silence." so... We "turned off our drones, and grounded our dreadnoughts-" yes, dreadnoughts. If it didn't hit you already, we are fighting a war, spanning planets after planets, both habitable such as earth, or as volatile as mercury, during the goo's time of discovery... This is the pre Logue to the grey goo's malfunction and the discovery of the beta... ( we also stopped venturing out into space because we couldn't find any other sentient life, and now they did. Might play into the future of this universe hint hint).
EDIT After watching the Gamescom video, and now knowing that ships are constructed by private companies, its seems something else is occurring. So in dreadnought, you are a mercenary captain trying to make a name for yourself in "a solar system rife(?) with conflict" this means we HAVENT gone outside our little area of space, which could mean that the story of the goo, is further away (time wise) than before(the goo allowed us to find habitable planets way far out, and only after so many habitable planets did we stop fighting).
Nonetheless it may still connect together, as there have been clues everywhere, from art styles to key words. This is all of the information gathered so far, and I can't wait to see what else is hiding.
