It's new to Ford Motor Company, but not to other manufacturers. It's found on several engines in Europe and Japan. Both naturally and unnaturally aspirated.
The reason it hasn't been seen here before is because our gasoline is so poor... it tended to clog the injectors. New injector technology makes that less likely.
This is one of those technologies that is good for everything: efficiency, performance, mileage, emissions, drivability.
One side note:it does require engineering work in the cylinder head since the injector is in the head rather than in the manifold. On the latest generation Audis, this required them to move back from 5 valves to 4 in order to have room for the injector.
