We have a few new screenshots of Tales of Xillia from 4Gamer, mainly of Leia. The ToX official site has also been updated with her character page.
Both 4Gamer and the official site lists Leia's name as Leia Rolando. That would be her name's official romanization. The official site has also been updated with info on the country of Ru Rondo. Pretty much most of the information is old news and has been covered already here and here.
