Re: Mass Effect Andromeda
I mean, even if they were working on it right now, they wouldn't be able to tell just yet. They have announced they are working in a mass effect game, they just haven't specified which one. People like me, who enjoy the original trilogy but also liked Andromeda, can only wish they actually continue with that story.
And as far as I know, is not that they abandoned Andromeda in favour of Anthem: just like with Dragon Age, different teams were working on each title. If anything, the extremely bad reviews after launch made EA think maybe it wasn't worth the hassle, and that's why they might have cancelled The Quarian DLC.
If you want to know what happened with the Quarian Arc, you can try to get "Annihilation", a book that narrates what happened to it prior to Ryder finding them.
