Heya:
I most likely played the exact same demo that Henry did, though I was at the San Diego Comic-Con (mini-review in another thread). It was absolutely a demo/test version, which is why the extreme slowdown on the Save/Load screen didn't really bother me, and I expect the relative slowness of movement and window scrolling to be improved as well (I don't want it to slowly accelerate to fast movement, I want it to be fast right away, it's my fault if I have the mouse at the edge of the screen accidentally).
The interface on the other hand, I totally like, especially now that I know you can A) drag the action radial menu around and B) center the screen on the selected character. The actions and information in the interface are super easy to read (possibly it's time for glasses for me, sadly) with full spell names, ability names, etc. No icons (or de-emphasived) icons, woo!
I'm playing KotOR now, I'll play Lionheart soon, and I'll play ToEE as soon as it appears. Lots of CRPG gaming goodness this time of year, oddly enough.
Take care,
Dreeble
