According to Blend Games' report, BioWare community manager Jay Watamaniuk revealed the team are in fact working on a new piece of DLC.
Before they could extract anymore from Watamaniuk though he "steered the conversation" toward the upcoming PC patch, which he expects to be ready in two months.
"Watamaniuk mentioned earlier in our chat that a second Mass Effect DLC episode was on the way," writes Blend Games. This slip came from the New York Comic Con while speaking with BioWare.
It was revealed that BioWare were in fact discussing new DLC for Mass Effect last year in August, and it was bossman Greg Zeschuk who revealed that at the time.
Bring Down the Sky was the DLC released for Mass Effect and introduced a new species to the game only before mentioned though the in-game codex; the batarians.
Let's hope there's some truth to the report!
