Good deal if you're planning a console upgrade soon.
Electronic Arts has announced Cross-Buy support for any Dragon Age: Inquisition downloadable content. This means that if you buy it on older systems, you can play it on the newer consoles (and vice versa).
As is typically the case with such deals, this only works within the same console family. So, PS3 to PS4 and Xbox 360 to Xbox One. The first DLC to support this option will be Jaws of Hakkon, which hit Xbox One and PC in March and finally came to PS4, PS3 and Xbox 360 last week. So, if you're in the midst of a generational transition or you see that happening soon, don't despair. EA has you covered.
But you still need to find a way to keep playing Inquisition with The Witcher 3: Wild Hunt available and Batman: Arkham Knight coming in June.
