They have replaced a pure mechanical linkage with a motor in each valve.

A typical 4 cylinder engine will now need sixteen extra motors to run it.

While I like the idea of controlling the timing of each valve interdependently for the other, I am not for the additional electronics in the engine.

Its even worse, they replaced 1 camshaft with 4 camshafts, because electric linear actuators are not there yet (and probably never will be).
