There is a new interview with Ossian Studios, developers of the first announced "adventure pack" for Neverwinter Nights 2. Game Banshee posted the comprehensive article. Here's a portion of the interview:

GB: Are there any major differences between working on a Neverwinter Nights 2 module as opposed to a Neverwinter Nights module?

Alan: I think the most important development difference with the NWN2 toolset has been the level design. Areas in NWN1 could be very easily built, although a skilled builder was needed to create high quality ones. In NWN2, the amount of time needed to create an area, let alone a high quality one, is markedly higher. For exterior areas that use a heightmap, this is to be expected, but building interior areas requires significantly more time than NWN1 as well. We are very fortunate to have found some extremely dedicated and talented level designers. In fact, MoW's area design is something that should really stand out for players as one of the highlights in the game, since we took a lot of care to make them as detailed and intriguing as possible.

Regarding the "bridge" between NWN 2 and Mysteries of Westgate:

GB: How will Mysteries of Westgate tie in to the NWN2 and MotB campaigns, if at all?

Alan: MoW's story doesn't tie into NWN2 or MotB at all. We wanted the freedom to develop a top-quality story without having to work within the plot constraints from Obsidian's two games, so that called for a separate storyline entirely. Besides, MoW was developed in parallel with MotB, and we weren't developing an epic level game, so dependency on the expansion wasn't an option.
