It appears that the sixth volume in the Amulet series is being pushed for a later date. According to an official Twitter response from the author (Kazu Kibuishi) back in July, the book doesn't see completion until about December (though a release date is unheard of.)

Kazu also confirmed in a more recent response that the book will, in fact, be postponed for another year.
