The bundle features the Snow, Lightning, and Sazh episodes, as well as three weapons, seven costumes, and six Coliseum opponents. Gematsu has the full list. Also, the DLC from the Collection is coming in its own bundle to PSN and XBLM.
Square Enix is also re-releasing the game in the country under the 'Ultimate Hits' label. That version arrives in stores on the same day, but also on PSN and XBLM two days prior.
