The original systems all those years ago were really held back by the speed of computer chips that were available at the time. They are trying to make the suspension respond as quickly as a skiers legs absorb hills and allow them to lean into turns. The thing they seem to have missed is that the skier looks ahead and anticipates what is going to happen instead of just responding to a bump. A blind skier would not do nearly as well. So, what they need in my opinion are sensors looking ahead at the road to determine what the suspension is going to need to do before it happens.
Check out the ride height on that demo car. There is a lot of play in that suspension to account for the response time of the system. It does stay pretty level, but you get a very high center of gravity. They are also not taking it to the next step, like some other systems have, to make it actually lean into turns or tilt back under braking.
