As you can see in this document, the Source engine (just like UDK) uses lightmapping information to affect the lighting situation together with normal maps. This makes a lot of sense. This way all the static lights can contribute to the normal mapped lighting. And there are no additional dynamic lights needed to influence normal maps / specularity. It even renders very fast.

Yes, that will be nice. A directional baked lightmap will surely render faster than dynamic lights. Plus the model can get the light direction from static lights too(so they'll have bright part and dark part instead of having uniform brightness)
