The mysterious something in the works has been revealed. According to the spokesman review, Cyan Worlds will be putting the future of Uru further into the hands of it’s fans than previously intended, by releasing the source to the game servers, client, and tools, (Weren’t they going to do that to some extent under the MORE plan?) as well as run a dataserver serving the Myst Online content. The difference appears to be that they will not be actually hosting the game servers themselves, but will be allowing the fans to take control of the indvidual servers much as they did during Until Uru, except this time possibly with the ability to further develop the system and fix bugs. 

Discussion of this recent development has begun to accumulate in the various forums, and the news has appeared in a few other places as well. 

Personally, I remain somewhat skeptical, as I don’t see exactly how this would require less work on Cyan’s part than MORE did. However, this is certainly a hopeful development.
