Details are pretty scarce, but rumor has it that Cryptic might be working on a Neverwinter Nights MMO. The information was not officially confirmed nor denied until now, and this will probably not happen for a while now. However, it is indeed an interesting rumor.
According to Variety: “Sources tell us that the developer is working on a massively multiplayer online (MMO) version of ‘Neverwinter Nights’ with an eyed 2011 release.”
And these are the only details. Not much, really, but just the prospect of having a MMORPG based on Neverwinter Nights is great enough, right?
