There is more of a difference then just 7.1 to the sound. The PS3 has the ability to give uncompressed HD audio, while the Xbox 360 does not.
So if they have uncompressed audio available for FFXIII it will make a difference if you have an audio setup capable of HD audio whether or not you have 7.1, 5.1, or even 2.1
