It’s coming to Japan this year for the PS3, we know that much, and we also know it’s coming to the Xbox 360 in Europe and North America sometime after it with the PS3 version, but when? “Within a year” according to producer, Yoshinori Kitase.
In an interview with Videogamer, he states:
Obviously we would like to release it over here as soon as possible. Traditionally the Final Fantasy numbered series, it takes about half a year between the release in Japan and the release in North America, and another half a year before it’s released in Europe. But we would like to minimise this, this time.
He’s also confirmed that recording for the English dub for the game is now under way:
For example we have already started recording English voices, and also the text localisation has been in progress, too. Normally we complete the Japanese version first, then move on to the US and EU versions, but this time there are some tasks that are happening simultaneously. So this time we’re hoping to release sooner than a year later than the Japanese release.
Considering they’re now doing the dub for the English version, development on the Xbox 360 version must be under way by now.
