Seems to have a huge mish-mash of designs from other Zelda games. The Bokoblins follow the Skyward Sword design; the Stalchildren and Great Fairy from Ocarina of Time; Argorok (the shiny black dragon) and the ReDead knight are following the Twilight Princess design.
Unfortunately, the combat doesn't look like something I would enjoy in a Zelda instalment. I'll probably end up buying it in the distant future, when the Wii U is much cheaper.
