I think it just depends on the game. I remember when Lost Odyssey on the 360 came out the "Asian" version was released at the same time as the Japan version and the Asian version was in English. Though the Japanese and actual Western releases of the game were fairly close(about 2-3 months difference), so I'm sure they were already finished with the English translation and everything.
As for FF13, it probably won't be released in English so soon since the Japanese and Western(US/Europe) releases are pretty far apart. Don't quote me on that though ;-p
