I’ve been following for a while but not holding my breath. Seems like it’s been close to release for years. Some of their later blog / Twitter entries mention save-game trouble, though I wonder if it may actually be a lack of time devoted to the project.
Considering the legacy user base and guaranteed press coverage it could be there hasn’t been much pressure to release it sooner. Then again it’s not clear how much time they’re able or willing to devote to it either.
