This is from the show-floor at E3 so you can't hear the sound in the game, but you can see what they are playing. It looks really good, but there seem to be load times, I hope they fix it.

Jeux-France Stream (Click Vidéo Final Fantasy III (27 MO) to stream the windows media player video).

YouTube version (for those of you who don't like to stream windows video).

I don't see a downloadable link on their site or I'd provide one as well.
