I heard of another manufacture already doing this but cant remember what one.

I was reading an article the other evening where BMW argue the efficiency using their valvetronic system, is similar to cylinder switch off.
They illustrate it like "dimming all lights" rather than switching off half of the bright ones.
Makes some sense, and I'm sure BMW will have tried both methods. If efficiency is close, it would be reasonable to stay with valvetronic and make advances with that as the core technology.
