Eliezer says he'll do a progress report on 11/1. I haven't heard any news otherwise.
I don't think that 'Eliezer's book' refers to HPMOR. I think it is more likely that he is asking about the book based on the Sequences (for which this is probably the most recent thread).
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
