User blog comment:J Shepard/Mass Effect 3 more DLC!?!?!?/@comment-1679409-20120313175248

Almost assuredly. I would imagine they could add some stuff in multiplayer like more classes (krogan vanguard, anyone?). We also never land on the home planets of the elcor and volus (though we go to their systems). We don't even get to go the system containing the hanar homeworld. And even though we see that the systems containing places like Illium and Omega have fallen, we don't get to see it. So, there's room for story-based DLC as well.
