Dengeki Playstation 25/04/2011, new game information inside ?

I doubt they started to work on an expansion/add on already, unless you just mean they want to make sure the PS3 version is launched once everything that people should've had from the start is implemented, then yes. But all that stuff will definitely be in the base game...no reason an add on would be needed for just opening Ishgard among other things.

I'm almost convinced they have been holding back content and diverting resources to an expansion for when the PS3 version launches.

Would explain why they have been so god damn slow.
