Yes, they're almost certainly going to do it a 3.x release. I think in some senses these backward compatibility breaks have already happened. I remember that Google got bit by async becoming a keyword in I think Tensorflow. Generally a lot of old Python 3 code still works today if it doesn't do anything really weird like that, but I do definitely think that the pain of Python 2 to 3 was painful so they don't really want to repeat it. I think it is probably prudent to treat point releases as major releases at least with regards to Python.
