Can anyone point out certain points in GOW 2 they might put in GOW 3?

That is, if they make a third installment to the Gears Of War series. A few things I can point out is Dr. Niles attempting to 'save' the children by kidnapping Locust drones for unknown research, Dizzy's reappearance and along with Adam Fenix's 'Back from the Dead' routine. Anyone else have any other ideas I might have missed?
