You don't need any specific information. All you need to do is take everything SOE has done in the last 10 years, then watch the keynote from last night and just imagine what this new game is going to be like. I mean you have EQ which was a successful accident. You have EQ2 which has been panned by the majority of MMO gamers (terrible combat, UI, graphics, etc.etc.). You have DCUO that launched without a function chat system, missing content, and no end game. I don't even know what Dragon Prophet is.
They also seem to love to show you all the gaming press awards they get as proof, and not sub numbers or anything. Ps2 #3 best shooter of all time according to PC Mag? Eh.
PS2 seemed to have been received pretty well by Planetside people so that is the outlier. If you think the job they did with PS2 can carry over to EQN then there is a chance, but the track records doesn't give you much to go on.
