Hell I don't remember! I have always hated the fact that they (BMW) tends to trickle out technology that's really cool and seem to add it to models without much thought. For example I believe the adaptive headlights debuted first on the three series first. You would have thought they would have reserved that for the 7!?!?!? It makes sense to wait until a midlife refresh but I'm now on the list for a 2009 so I hope it makes it! This is what BMW needed when they introduced "flame surfacing".
Just came across this thread as well:
