Okay, I see where you are coming from, but I don't see this as reason for concern. Based off that post and after a quick analyses of the questions asked:
 * It's not Hero, Volume 2. That's been announced that they are working on it, therefore not super secret.
 * It's not Bloodbound, Book 2 for the same reasons.
 * Ditto with The Elementalists, but mostly because they have shown us art from that, barely, but they have shown us art from it. We really know very little, but it's not really a secret project.
 * Although I doubt it, it could be Most Wanted, Book 2. They have repeatedly told us that they aren't working on it right now, so if they were trying to surprise us, it would definitely be super secret.
 * It's almost definitely not coming out this year, whatever it is. If they are just getting concept art they are way too early in the planning for something that starts in the next three months.

So yeah, I'm pretty confident it's not anything that's been announced, but I also don't think it's coming soon.

Thank you for giving me that link so I could read it. That helped.
