Thanks to Nwvault for the info and links:

More news and screenshots are becoming available as E3 continues. La Bibliothèque de Neverwinter Nights has new images including the box art. Also included are what appears to be some very early stages of city areas. Rashemen houses in the screenies are apparently placeholders according to Obsidian Designer Jeff Husges.

Gamespot, Gamespy, and IGN all have more info about the SoZ scene at E3. Every one mentions the new party features that are on the horizon, and the world map renovations seem to be a big topic as well.
