Well you have to remember that any energy going into moving the valve is completely lost vs. with a camshaft you get most of it back. The Fiat Multiair system has that problem too, it loses all the energy in the valve spring in some modes. How significant this energy is, I don't know, but the valves in a car engine do have some significant mass that needs to be controlled.
Still, it's great to see that they've been running camless valves for 2 years, I'm sure not many other companies can say that.
