No word at all on future DLC yet beyond the fact that it's coming. If the release cycle will be anything like it was for ME2 then we're probably looking at another 2-3 months minimum before the next major DLC. They may of course to other smaller bits and pieces in the mean time like the weapon, armour & alt appearance packs. We'll see. It's a fair bet though that one of the DLCs will have something to do with helping Aria retake Omega.
In other news, the Paragon Lost trailer is out.
