Ossian Studios have been toiling away on a Neverwinter Nights 2 expansion for years now. Like, it was originally due in 2007. But now, in 2009, it's actually coming out!
Called Mysteries of Westgate, it's boasting a campaign that'll run for around 15 hours, and include new monsters and presentation stuff like new voice-over work. An announcement on the game's forums from earlier in the week confirm that the expansion - which will only be released as a digital download - has ironically "gone gold", and should be released soon.
