Out of curiosity, who else has tried to put an MMO on a current gen console? I can't think of any off the top of my head. PS2 had a handful (some still running, others either going to be shut down or shut down long ago). I know CCP is coming out with Dust 514 in the next year or two, but other than that and DCUO I can't think of any others. For an MMO to work on consoles you would have to pretty radically change the entire game from what is normally expected because of the wildly different control scheme and the fact that the ability to communicate isn't a guarantee (if you play a PC MMO, you have access to a keyboard. You don't necessarily have access to a mic with a console) mean you have to do some things very differently. It's dangerous since your exploring new areas (dare I say...innovating, or at least attempting to) and most big companies are afraid of making such a risky investment.
