They have a staff of 200-something employees working on the production of Final Fantasy XIV according Wada in the first Live Letter.
Also Yoshi-P has commented at least two times if I recall correctly that they have many different teams that do many different things, in particular there is probably an internal team who goes around and collects data from the Development Team so the Development Team can continue to work, if you think they (Devs) don't have to make a progress report every few days on what they are doing then you must not have worked on anything large scale. As a person who has been a Stage Manager I had to give progress reports every night after rehearsals and after production meetings to the appropriate channels that requested the information.
To deny those kinds of people exist is your own fault and your own lack of knowledge in the way a large scale development team works. Basically saying the Development Team can still work like they are now and give us detailed information because they have to do it anyway when they report in, its just that for whatever reason they are deciding not to.
EDIT:
Also its the job of the Square-Enix Reps to do the translations, the Development Team is not providing the information in anything but Japanese more than likely, as I seriously doubt they are being requested to give the progress reports in all the different languages...that would be silly and a waste of time if they were.
