Yeah, I don't see any Quarians being in Andromeda tbh. The Krogan I can understand since they're not as tight knit a group, and there will be Krogan who are part of of clans that oppose Wreave/Wrex, but the Quarians? Nah.
So you think they're not going to have any representatives from the race of one of the most popular companions in the ME series? A race that is known for and expert in travelling long distances through space. A race that doesn't have a homeworld (and not all of them want the old one back if they can find another one they can survive on - and though that is non-trivial, Andromeda would be a good place to look). Really?
If they don't have any Quarians in ME:A, it'll certainly because they ran out of time/budget, and I guarantee they'll either add them in DLC or in ME:A2.
Most likely they'll at least have one fully-suited one as a placeholder/marker. I'd be surprised if they had Vorcha or Batarians, though (the former would be easy to introduce later if desired, of course).
