Ok yes, DX11 is nice, but, come on, look what crytek achieved with crysis 2... If they had used dx11 probably there would have been a lot of people (including myself) that wont be able to push the graphics to max. I can't even do it with dragon age 2. Even if I could, crysis 2 still looks better on "Gamer" (minium graphics settings) than most games out there.
But enough about crysis and dx11...
What I think Beth should think about for Skyrim, is adding some stuff like motion blur, so when you swing a sword it would actually look like moving fast.. to feel the kinetic energy, you know a lot of movement and hammer/sword swings will be present :brokencomputer: :toughninja: so that could add a lot to the visuals and overall feel to the game. Other stuff like ssao are welcome. So, I don't think dx11 is that necessary right now.
look at this example from crysis 1

Now let's dream... (motion blur: on)
Imagine a big dragon swinging its big wings flying towards you..
A group of wolves lurking in the dark.. you get to see only a blurred shadow behind the foliage and you don't know what it is
Arrows or spears (if they ever get into the game) passing very close as you run to get cover
Walls and rocks or traps falling over you or some unlucky npc
I think it'd do well in the game. What do you think?
