I'm not sure what everyone's beef with the Shoshone are. Maybe they aren't well known outside of America or maybe my schools were a very long string statistical anomalies but from kindergarten (the stories of Sacajawea) to college (Occupation of Yellowstone and confrontations with the park rangers, the tourists, and the army) I was taught about the Shoshone in one way or another so I really can't relate to people who say they were a throwaway pick or just used to fill space or whatever. They always seemed to pop up in my education and a lot of pop culture on plains Indians is directly inspired by Shoshone culture or an offshoot of theirs so I assumed many Americans would come to their defense if nothing else. While the Shoshone aren't a favorite tribe of mine (would've LOVED to see The Pueblos and was very sad to hear the story of their refusal to participate) I have no problems at all with their inclusion and don't see why people are kicking them into the dirt so quickly.
As for Austria with the storm that brewed over splitting Macedon off from Greece and making 1/8th of all the playable sides Hellenic when there are so many missing groups from all over the world I feel like splitting up the Germanic cultures at this time would be inadvisable. Down the line I'd be down for Austria but if they were added right after Macedon and Australia (A cultural child of England) when we still don't have people like the Ottomans, Mongols, Inca, or ANYONE from South East Asia I'd probably roll my eyes so hard they'd pop clean out of my skull.
