MTV Multiplayer has word from their conversation with BioWare co-founder Greg Zeschuk on the possibility that more downloadable content is coming for Mass Effect, the science-fiction RPG. Dr. Greg is guarded, but seems optimistic:

We’re talking about that. You know how we are. We’re always very circumspect until we can go “Aha! There it is!” With everything we build now, we want to have this long-term relationship with the customer and always have something for them to try. So we’re definitely looking at that for “Mass Effect.”
