You know? The other day I thought I was misremembering Jim's post and that I had misunderstood. That he meant that the next Harry's book would be published at that time. But then I reread the actual post and...I think he talks about Dresden.
First of all, he says it in the same line than the "finished the first chapter" of the DF book. The part about the Olympian Affair was in a separate sentence, as in a small paragraph of its own. But the most important part for me is that he said "writing". He is not going to write Olympian Affair anymore, so I understood he meant writing Dresden. But perhaps he was the one who made a mistake, and he wanted to say those weeks were until publishing time (of Olympian). I do not know.
Whatever the case, I am celebrating I will see the Cinder Spire characters again.
