From the details in KS this game will launch in Dec 2016. 6 Months after the Camelot Unchained expected launch date. It will be interesting to see which project is on target. Because I don't personally think there enough hardcore PVP players to split between 2 games..
I would assume that all major pvp guilds would want to participate in both games.. Winning in one game and not attending in another is not really a thing these days is it??
