Not yet, however the first trailer for this game strongly hinted that there's more to come on that. One of the devs was interviewed as well recently and was asked a question about what is chasing the Vasari. He didn't want to talk about it just yet.

Just finished a 7-hour game as TEC Loyalists vs 4 Hard AIs. Damn, that was insane. I was in doubt several times whether I'd make it or not, but the infighting among the other factions proved to be their undoing. Ended up getting 5 achievements for wiping them all out. ^^
