This is something small, but worth mentioning, I guess. The English Dissidia website has finished its updates with a full character roster (minus Shantoto and Gabranth) and the E3 trailer is up. If you listen to the trailer, somewhere around the middle, you can here some of the character's voices or, to be more specific, Garland's "argh", WOL's voice, Cloud's voice, Kuja's voice, and Zidane's voice. Nothing big, but I found it interesting.

P.S. I don't know if those idiots who made the site realized it, but if you go to Zidane's profile, it's horribly misspelled "Zidaine", just putting that out there.
