Camless is not as simple as it sounds. The issue with camless is that it robs a lot of power.
A conventional camshaft does not take all that much power to rotate, because after the valves are forced open against their springs by the front side of the lobe, the spring actually helps the cam rotate, pushing it along as the valve retracts against the backside of the lobe. Power required nets very little.
When using hydraulics/electronics it is very difficult to recapture the energy released by the closing valve back into the rotation of the engine. Many manufacturers have been trying hard for years but there are on success stories yet.
