犬耳家の親族, a fansite dedicated to Nobuo Uematsu's music company, Dog Ear Records, has released a DVD to its members that gave a small look inside the studio where the main theme for Final Fantasy XIV is being recorded. Recently, Square Enix announced the vocal artist for Final Fantasy XIII's main theme, but all the DVD appears to reveal is about FFXIV's grand motif is that the artist is foreign.

It was stated in an interview that the most vital points of FFXIV's story would have spoken dialogue, but only in English for all regions. This would seem to indicate the main theme will be sung in English as well, but there is no confirmation yet as to whether there will be versions sung in other languages.
