Sure, we all knew it would be published in the next few years, but here's an update – from the author's blog back in December. The five month old news is that (1) the text has been handed in to the editor at Tor, and that (2) there were inter-version technical problems with MS Word. (Can I get a "Ah kin relate," my brothers and sisters?!?!?) No updates since, presumably he's on vacation. I'm just guessing, but the target publication date may be sometime next fall. (Guessing? More like hoping.)
Part 1 was good (my comments here and here). I'm looking forward to this one.
