Hmm.. seems like HiG have decided to more and more go down the route of re-releases/updates of older products, rather than fully new things.
We've seen the new Kinder of Carcassonne, and now Hunters and Gatherers...
As they say it will have revised rules I'll hold off on passing judgment, but as still. It's been a long time since we've seen a big expansion for Carcassonne itself. Maybe they want to focus more on other games or mini-expansions, which I can understand, but I'm not too sure yet about re-releasing older products with a revamped look
