Girl in the Glass delayed

According to a Barnes & Noble e-mail I received today, Jeffrey Ford's new novel "Girl in the Glass" has been delayed and a new release date hasn't been set. (However, the link at the site still shows it will be published Aug. 16.) At the same time, Ford has suspended his message board at Night Shade Books. Originally, there was a note on the boards saying he needed time to work on a novel. That note has since been removed.
I don't think this is that unusual in publishing (I have little to no inside information on the publishing industry, so this is all speculation), but I find it interesting. Will the novel now be significantly different than the one reviewed by Kirkus, Publishers Weekly and Emerald City? Either way, I just can't wait to have this book in my hands. I'm also patiently awaiting "Cosmology of the Wider World," (review here). Ford had mentioned that won't be coming out before September.
