HD wont get rid of displacment maps......we just wont be restricted to making things look HD by using displacment maps.

Now displacment maps can be used more properly to how they were designed. To add extra displaced detail to textures.

With HD morphs we no longer need to use displacment to do gross shaping to the mesh, We dont need it to add muscle detail, to soften mesh into a more organic look, to bump out areas for growths like horns. We can do all that with morphs now, like things should be done.

But we can still use displacment to augment texture details that are not so morph specific. So that adds a new level of versitility to both content creators and content shoppers alike.

It is all very cool!
