I'm pretty sure that most GDI engines still have throttles. Some may only be used for warm-up (I think I've read that somewhere) but I am pretty sure that most do control the engine load with a throttle mechanism.

I wondered about this, too, but according to this article aerohead's comment appears to be true, at least for current state-of-the-art GDI engines. The best of all ICE worlds, as it were.
