I believe that gamespy has a set of three screenshots from ToEE as part of an interview article they just put up. The shots look rather nice, with little avatar pics at the top, lined up in intiative order (PCs and monsters).
The graphics look nice, and one appears to be on the Fire Node, I'm guessing. It looks like the interface will be fairly clean, and supposedly will be using the 3.5 rules. The design team sounds pretty knowledgeable about D&D in general (enough to note the oddness of a giant having a 17 Charisma, for example) and claim to have broken out the original module and played through it for research purposes (as well as having played it back in the 80s).
