There was an exciting announcement on the Bioware forums today. The team that brought us Baldur's Gate Reloaded for NWN2 is working on Shadows of Amn Reloaded (SOAR)!
It's still a long ways off, but this team is nothing if not tenacious.
Update: drechner has a new post on the bioware forums with a long list of specific changes in development that their team is planning for SOAR. I won't copy the whole thing, but it's written with the air of someone who has learned a lot from his process.
These folks love their game. I'm so impressed with them.
