It had been rumored before, but rumors have surfaced again that Atari might soon announce that they're working on a Neverwinter Nights MMO. This because apparently during GenCon 2010 Atari said that they'd announce 'something' about a D&D-type game and Superannuation dug up some domain names Atari has registered. And that's pretty much all there is to this news so far (you can read the full news at Blue's News). Supposedly Cryptic (who made Champions Online and Star Trek Online) is working on the supposed MMO.
Of course, if it is an MMO then that just shows how completely they're missing the point of what made Neverwitner Nights such a great game (being able to create your own modules and run your own servers and such), unless they're doing something really different from the usual MMOs.
The rumors are given some credence by some news that I reported on before, namely that WotC is suing Atari over unauthorized sub-licensing the Dungeons & Dragons digital game rights.
And of course if there is a new D&D game, whatever it is, then it's almost certainly a 4E game.
