You can see the planes a bit in the Dread Gazebo flipthrough: http://www.youtube.com/watch?v=_V9gB9tvKZI (jump to 55:26).
Yes, that's what I was using to puzzle out my guess for the planar structure in 5e, but the image quality is really hard to make out details. I get the basic shape: rings within rings. But I don't get the exact layout of how the Ethereal and Astral connect, where the Postiive and Negative are in relation to the Lemental Planes, or the names of the Outer Planes, or, or....

I still have my question. It's ok if I get no answer, I'll get my copy on the 19th.
