The word 'revolutionary' in the games industry is about as meaningful as the word 'gourmet' is to food. Everything is revolutionary now. Please pay no attention to the fact that there are already dozens of free to play mmo style games like Global Agenda or Warframe that feature a central mmo hub city and instanced multiplayer missions. Damn, I can't wait to play the Witcher 3 when it comes out to see how a good developper spends their money.
