It seems like there have been more leaks about this pack than usual. More than Werewolves it feels like. It makes you wonder if those leaks might be orchestrated. This is what the third or fourth leak? We knew the theme of the pack while we were still waiting for Werewolves to drop. Then the world map leak, now this leak about the gameplay and the update. Maybe this is normal, I'm not entirely sure. I never started paying attention to the news ahead of a pack release this closely until I started participating here which was just before MWS bombed dropped.
Maybe these 'leaks' are to help mend fences after the MWS fiasco? Just a thought while waiting impatiently.
