Stormblood official release codes will not be released until later, alternatively has until the 23rd (Or so I understand) to register the code. If he bought Stormblood and ARR from SE, then it'll auto roll over and I don't /think/ you'll need to worry about it. However, I am unsure if he'll be able to access stormblood since alot of content is locked behind Heavensward espansion.
