I can't share details yet, but within the next couple of weeks I should be able to. We're working on something much bigger for the game than "just" the complete art revamp, as it turns out. This is something I've been thinking about for a while, but couldn't figure out how to work out. Now we've figured it out, and we're working on a lengthy design doc to make sure all our ducks are in a row so that we can hit the ground running on implementation with this.
Anyway, I know this is cryptic and largely unhelpful, but I just wanted you to know that there is an enormous amount going on with the game at the moment. I'm going to stop doing the weekly spells at the moment, and largely the other bugs that have been reported lately are really slight. So we're throwing ourselves mainly into this new stuff for the moment when it comes to this game, while also of course working on AI War and Shattered Haven.
I think everyone here will be pleased with what we're working on, it's just not quite the time to reveal it yet!
