It seems VGMDB.net was leaked the first details on the Final Fantasy XIII-2 Soundtrack. As with most Final Fantasy soundtracks, XIII-2’s will be available in two flavors: standard and limited edition.
The standard edition will consist of 4 discs and a price of 3990 Yen. The limited edition version will come with four extra discs, along with an extra DVD that will possibly contain trailers from the game, similar to Final Fantasy Type-0. The limited edition will likely have other bonuses such as specialized packaging and will cost 4800 Yen.
Both versions will be released in Japan on December 14, 2011, one day prior to the games release.
