When is Online Co-op Disconnected?

When you develop a game, based around your ability to communicate with your partner and there is no voice chat for on-line co-op... EA, you are a smart dedicated publisher that makes quality games. Why was this overlooked? I understand Microsoft gives you a freebie with cross game chat and you obviously had enough money to put in some chat function, since you were able to make a PSP version of this game (is that even going to sell). Sorry, getting a little bitter, but I think this should have been in there. It is just what the consumer would expect going into the experience. Good game though otherwise and the mask customization within the EA accounts was genius, but next time, please put in the voice chat. Thanks!
