'Mass Effect 2' DLC Plans Reaffirmed By BioWare

BioWare has thus far remained true to their commitment to a "continued stream of DLC" for "Mass Effect 2," and they plan to continue on course, even after their "Kasumi" and "Overlord" packs. In fact, BioWare says there are still "big plans" left to be realized with "ME2" before they release the "Return of the Jedi" of their trilogy.
"We still have more DLC in the plan for 'Mass 2,'" BioWare co-founder Greg Zeschuk told VG247. "The last ones were really well received. People were really, really impressed with the Overlord Pack, and the Kasumi one did really well too."
There will eventually be an endgame, though, which Zeschuk freely admits. The frequency of BioWare's DLC releases could decrease as well, but they will keep on coming for the time being.
"It's at the point where it'll probably diminish a little bit, but there are still some pretty big plans for DLC," he said.
Personally, I'm anxious to see where the DLC goes and how critical it becomes to the narrative, since BioWare has said that they want to use future releases to connect "ME2" and "ME3." That hasn't happened yet, but they've still got plenty of time to work with.
