The most likely outcome is none of them are going to be expanded. Eva has disappeared, quite possibly from overworking herself trying to take on Jim's projects before finishing her own. If so this means we lost a promising new writer because of people's refusal to accept the departure of an old one. I am angry about this.
Doing a project in the first place is a very difficult task and one that many people fail to complete. Trying to pick up another author's project is ten times as hard, because suddenly you're forced to adhere to their vision and their writing style, not your own. Trying to do it when the author was as wordy and as well-regarded as Jim is virtually impossible unless you're just as skilled as he is.
Consider them all done, because I don't think you'll ever see any more of a single one.
