I'll be surprised if isoku's awesome mods for water and fire will be invalidated.
There will be a bunch of other texture mods that must remain...night sky, skill screen, etc.
Yeah, I have to agree. Especially mountains, looks like they didn't do anything for that.
Here's a repost of some comparison shots I took:
People were asking for shots of NPC clothing and blocky faces:

High Res: http://www.imgplace.com/viewimg189/5/49adriannehires.png
Screenshots really don't do the hi-res pack justice, you have to see ingame.
One more comparison on an animal:

Edit: pay attention to the finer detail around the head, particularly the nostrils area.
