I just think that you overestimate the power of a producer under Sony.
All the projects DG has ever been involved in, in comparison to this one, have been extremely small. This game is being created by one of the biggest money forces in American online gaming, and believe DG is being watch and directed like a hawk. I have no doubt, even as producer, that he doesn't have as much control as you say.
There isn't much more I can argue with though yet, it's too early. There is still a stringent NDA in existance for beta testers, and the game is still a month and a half off from its projected release date.
I think we can all agree though, that it will be the best MMOFPS out there, since all it has to do is beat WWIIOL.
