Not likely. Nobody in their right mind wants the trouble and expense
of this sort of complexity in a daily driver.

Most of the complexity is in the computer control software and that
technology is already commonplace and reliable. The projections of
30% more torque, 30% less fuel and 50% lower emissions are very
compelling if they can manufacture it at a reasonable price. It
wasn't that long ago that multi-port electronic fuel injection was
regarded as too complex and expensive and now it's widely used. Back
in the early 1950s overhead valves were widely regarded as too complex
and unreliable. All it takes is more engineering development since
the advantages of variable valve timing are intuitively obvious.
