Yes it's official. Final Fantasy XIII on the PS3 does not have a bilingual version on the disc. I found out from a store worker (who will remain anonymous) about it. So now the only real reason to buy the PS3 version is for the game to have no data compression and if you only own a PS3. I was really looking forward to playing it in Japanese with English subs and now there is no escaping the English voices.
Hopefully the English voice acting is good, but I'll have to wait for March 9 to find out. Man that sucks!
