"Geometry" hasn't changed all that much, as I understand it. Head and seat-tube angles aren't much different. If what you want is less saddle-bar drop, that isn't so much a question of geometry as of frame size. A bigger frame will tend to put you in a slightly more upright position because your saddle height has to remain the same (determined by leg length) but the head tube will be taller. So if I were you the first thing I'd be looking at is whether your current bike is, in fact, smaller than you'd like. Ride a 58cm frame and see how that feels.
