Jump Festa 2012 is underway and Square Enix has revealed some upcoming DLC plans for XIII-2 at their booth.
First off, the Omega DLC will be available in Japan on 12/22. No pricing was given. Serah and Noel costumes will be releasing starting in January with the AKB48 winning costume and Assassin’s Creed respectively. In February, a swimsuit costume for Serah will be released… as a pink bikini.
Apparently Lightning will be featured as Colosseum DLC. She is said to be wearing her old outfit from FFXIII. [SOURCE]
