I just beat Gears of War on Insane and have some predictions. First who is the queen. From many forums and my own thought I think the queen is Dom's wife since she is missing. I'm guessing that the Locust was created from a experiment gone wrong or something due to their "ugliness." And also the figure seen in the end of the game is probably the queen (Dom's wife) and as you can see somehow she got "transformed" to turn into a Locust. Due to how the Locust were created I'm guessing it has to do with Marcus Fenix's dad. Also why can't they stop fighting (said at the end of the game.) I say they can't stop because something below them is rising and they have to surface to survive. Or it could be a fight of religion (due to the cross like symbols on Locust weapons.) The Locust (grasshoppers) are like insects due to their many eyes and they live below ground. But the biggest similarity are bees since the names of the groups and also they mention "beehive" when they see the cave routes in Marcus Fenix's dad's house. RAAM is the "king" of the game also known as the breeder since he is the "General." If you look at this game in another perspective you could think that the Locust's aren't the bad guys but the humans are. That's it for my predictions.
