@ the final fantasy section of the podcast.

one of the people wasnt too sure about the 360 live stage demo and said it was japanese, but if you go rewatch it on youtube everything is in english, now if you look up on youtube the final fantasy 13 ps3 demo you will see that it was in japanese only. From that research i would have to say it really was a snip it from and american version of the demo running on 360. oh and there was a LB(left bumper) icon above the ingame battle menu next to the word COM.
