White Knight Chronicles 2 Petition for "on-disc" content

Hey fellow RPG gamers, I am posting this thread to hopefully get some support from you all. Our player base has a petition up for more DLC content for the game White Knight Chronicles 2 and we need all the help we can get.

Basically there is content is on the NA/EU disk(s) but the publisher is claiming it is "Japan Only" and have dropped support, we are hoping we can get that changed and get them to unlock it by getting enough signatures (exact details can be found on the petition). If you want to take a minute or two and help us out it would be greatly appreciated.

Thanks for the help and spread the word:

Here are some pictures of the "on-disc" content we are trying to get released.

Earlier this week the publishers released some DLC Incorruptus weapons on PSN that we have been asking for so it looks like there is some hope for the quests we are also trying to get :)
