No need for an announcement because we've never given a release date - and we won't until we're confident that it's a lock. As we've said before, the Mongoose site is automated and has to put dates up way before we can be sure of them. Anything listed there is inaccurate unless it's also listed in our product section.
Right now, the only thing we're certain of is that the book won't be available at Origins. We're shooting for GenCon, but we're not going to commit to that until we're sure.
