There was an announcement that pre-orders from amazon would also receive a Yuna costume & victory pose, in addition to the Cloud preorder bonus that is already listed. I don't see any mention of the "spira's summoner" pack listed on here (not yet anyway). Anyone else know about this? Also, do you think these pre-order bonus costumes will be available for purchase if you don't preorder?
I'm sure the new DLC will be listed shortly. As for if they will be available later, yes, but you will have to pay. There is likely a period of time where the outfits will be exclusive to pre-orders too. There is also a DLC if you download the demo.
I think they will eventually release the costumes eventually, exclusive is more like a temporary thing. I eventually find dlc on XBL or PSN network in the future of what you missed out. I preordered the Limited edition one on squareenix website, it has the aerith DLC as a bonus as well (I really wanted the artbook though but aerith is an incentive)
