SE originally stated that they were going to allow offical user created addons and they would release an kit for people to make addons for FFXIV and that the best PC addons would get ported over to the Playstation. However the plans to allow addons kept getting delayed several times and they haven't really said anything recently regarding them. The whole thing seems to be in limbo at the moment.

I would love to see Yoshi P address what is going on with the user created addon support in the next live letter.
