You know what, this is driving me a bit crazy, this trade language which is everywhere and how LITTLE we know about this
The first picture is from Horizon so that I can show a clear image, but you can see it being used on Tuchanka, Sur'Kesh, etc and in different games as well, right? So it is everywhere from ME1 to ME3
And it bothers me a bit that some planets (ahem, Tuchanka!!!) won't show us a different language but then again, perhaps it's entirely linked to translators.
But the second image on the left: what we see on the Collector ship which I think might show either pure Collector language, or Prothean, or a hybrid version?
and the third image on the right: it's hard to tell at first, I thought it was like a mix of Collector and trade language, now I think it's just the translator of the data found in the first image as EDI is data-mining and a lot of information appears on screen:
