You can get a taste of what I've been playing for these past couple of weeks today with the newly released Lightning Returns demo. Look for their availability later today for both Xbox 360 and PS3.
You know about Lightning's outfits, don't you? If you nab the PSN demo today you'll get the Utsusemi Garb DLC, which includes the Heavenly Fan weapon and Kaminari shield. This equipment will be unlocked with the full game release.
The Outerworld social feature of Lightning Returns will be activated for this demo. Your final scores for the fight against the last boss will be submitted for comparision. If you beat that boss and submit your scores, the Siegfried outfit will be unlocked in the full game.
