, a member on FinalFantasy-xiii.net Forums (linked above), has found a leaked version of the Final Fantasy Versus XIII Trailer shown at Jump Festa 2007 which has never seen public eyes outside of Square-Enix's evil Closed Mega Theater.
To quote: We're not sure where this video has been leaked from, but we can only thank the Photobucket user a thousand times for uploading it for us. Thank God they have a good quality camera.
From what we can tell, this isn't the complete trailer, but is a good portion of it. The music is apparently from the final boss battle in Lost Oddyssey but I don't remember it. This trailer like all the rest is 100% CG.
