I found a rather awsome gameplay video here:
It shows all of the weapon skills and gameplay with pretty much every weapon combo you can imagine. This includes Mace/Mace Gameplay, Swpord/Sword Gameplay and Warhorn Gameplay which I have yet to see anywhere else.
One of the things I have noticed from the previous versions of the demo is the greatsword animations look more polished now. Particularly Whirlwind Attack where they seem to have increased the number of spins making the attack look much better.
