I think it's safe to say that the new aliens are enemies of the overlords. (hence the giant space cannon looking thing that was aimed skyward, at the incoming aliens).

But I think you got it right - the enemy of my enemy is my friend... at least until he becomes my enemy also. The new aliens didn't come "just to kill the overlords", because that would make for a very boring TV show. They have their own agenda and will most certainly become a problem, if not an outright enemy.

Damn, going to be a long wait for more.....
