Unfortunate that KDSS isn't std on non-AHC models. I had assumed it probably was. In fairness to Toyota - the non AHC LX has less ground clearance than the RX350. Not many people are in the market for an SUV with under 8 inches of ground clearance and also concerned about articulation on trails. I'm guessing that's where the GX550 will differentiate from the LX600. Presumably KDSS will still be offered in the new GX and 4Runner going forward. Hopefully it'll be the same system as the LC300 with two front cylinders. Would be nice if it were fully symmetrical.
