It is senseless to assume that there's no link to previous or other languages for the peoples in the setting. Otherwise the naming conventions of some of the races would be pointless and make no sense. In fact, from the main page of the game's site: "The Hyur champion personal freedom and liberty, and their espousal of an eclectic variety of languages and traditions is a legacy of their diverse heritage―as is their resulting lack of a unified cultural identity." it's obvious that at least the Hyur are aware of more than one language themselves. Some of the peoples in the land probably still hold on to some vestiges of other languages besides the common Eorzean spoken. That doesn't necessarily mean there are scads of people running around speaking completely different languages, though, so players should be careful not to abuse it.
It's also important for the players to remember as OOC information that in most fantasy settings a common tongue is a convenience for the players more so than the characters in the setting. Making up too many languages for the setting might work for the characters ICly, but might make the players behind the characters get lost or annoyed with the attempt at creativity.
