There is a silhouette of a joker!
I think (or hope is more correct) they will unveil that all the fairy tale adventures and so on was nothing else but a fairy tale, and they will introduce the new REAL lvl 50 stuff that is actually worth something. No adventures that gives XP wherer you dont need it, buildings that are a an upgrade instead of a downgrade and so on! I really really really hope they were not serious with the fairytale adventures, they wont last another 20 years if that is the way will do things in the future, that much is for sure!
