Direct from the GenCon floor, BioWare has announced their next title, called Neverwinter Nights. Here are the details, fresh from BioWare's homepage:

BioWare, the developer of the hit roleplaying game, Baldur's Gate, recently unveiled their next big project at the annual GenCon conference in Milwaukee. Neverwinter Nights, their new title, will be a multiplayer roleplaying game based on TSR's new 3rd Edition Advanced Dungeons & Dragons® ruleset. Set in and around the cities of Neverwinter and Luskan, in the far northern reaches of the Forgotten Realms® gameworld, the game will ship with a strong story, a powerful editor suite dubbed the Solstice Toolset, and the ability to enter the gameworld and modify it in real-time as an omniscient Dungeon Master. Neverwinter Nights will be powered by a variation of Omen, BioWare's own 3D engine developed for their visually stunning action game, MDK2, and will be published by Black Isle Studios, a division of Interplay.
