We're guaranteed a new Aragorn (hard to avoid spoilers, based on the name of the third movie and all). I can see them creating Eowyn and maybe a new Arwen depending on how they go with the final battle. A new, armored or battling Witch King Ringwraith, the required Mordor Infantry orcs, etc. Should be a nice assortment based on the improvements made between FOTR and TTT. Im also looking forward to seeing how the blue packaging looks, I have a "hue" in my head and can't wait to see how close I am!
