The Geth are an almost guaranteed no. The Quarians are a maybe.
There are totally Turians in there. I have the Havok and the Soldier.
Also the round dudes are the Volus. Man the Volus engineer was broken in ME3. It was hilarious.
Yeah, I said Turian by mistake. Edited.
But yeah, it feels like character races will be a bit limited unless they want multiplayer to break canon.
My favorite class in ME3 was the EDI Android class. And the one that was a straight up Ninja that could teleport and 1 hit kill most unshielded/unarmored enemies with a sword strike.
