The next Horus Heresy book, book V is coming soon. We are looking at an announcement coming most likely the weekend of the Horus Heresy Weekender. Here is what a customer service rep alluded to over the phone recently.

I'm sure this is pretty well anticipated by anyone who pays attention to Forge World's newsletter but I thought I'd pass it on anyway. While talking to FW's Customer Service about some Ultramarine and Horus Heresy Legion models I was ordering the other day, the guy on the phone told me to keep an eye on the internet the weekend of Feb. 7th. As that is the date of the Horus Heresy Weekender, I'm feeling safe to assume The Horus Heresy V: Tempest will have a release date announced.
