It would be difficult, from a storytelling standpoint, to do much else that would interest me in the Mass Effect universe. I've never been a fan of prequels, and we've already discussed the difficulty of putting anything after ME3 in the timeline. That said, I would be surprised if they're not planning something, just because they've invested a lot of time and effort into creating the game world, and up until ME3 it had all the earmarks of a long-running cash cow franchise.
