I think he is way off of the mark, let me explain.
MMORPGs were among the first games to push forward, and combine, all sorts of new and interesting technologies; digital distribution, social networking, persistence, and so on. These core technologies came to be associated with the EQ style games in much the same way that in the early 90s textured polygon graphics were associated with FPS games. It was into this world that DAoC was born, so it took that formula and adjusted it to match an aesthetic where players fighting players was the focus.
That world is gone. Persistence, social networking, and rpg-systems are in every genre of game, and several of those genres are MUCH better suited for a PvP focused online game. Shooters, MoBAs, and strategy games all take the place of the niche he wants to fill with his new PvP-Focused MMO. There is no room, or any real desire, for what it seems he wants to make. World of Tanks might be one of the best examples of the new breed of PvP MMOs. It takes a core game that is arena-based, and layers on top of that a browser-driven meta game that gives some real heft to the clan matches, leading to proper emotional investment.
The other, and proper, direction to go is something Eve-like. Now, I can't stand playing Eve because it is so mind-numblingly tedious, but I recognize what it does. It builds a framework of desirable resources through PvE, or PvAsteroid, for which control is required and players are motivated to fight over. Eve PvP is exciting and tense because of theconsequencesderived from the environment, which again emotionally invest the players.
I just don't see his old school middle ground DAoC-like game having a real shot.
