Bioware has announced that more DLC is currently being developed for Dragon Age Inquisition. Unfortunately, all future DLC will be released only on PS4, Xbox One and PC, which means that it won't be available on PS3 and Xbox 360.
It's not all bad news, though, as Bioware has launched a save importer that will allow players to carry their save files from PS3 to PS4 and from Xbox 360 to Xbox One. You can click here to check a step-by-step guide on how to transfer you save files. In addition, any DLC purchased on PS3 and Xbox 360 can be downloaded for free on PS4 and Xbox One, respectively.
For those interested in getting the Xbox One version of the game, keep in mind that Dragon Age Inquisition will be added to EA Access this Summer.
