I would say 'yes' but it's not really an easy answer.

You have to define what 'Germany' is in the first place, the way I see it (as non-German), Germans from north are quite different people from Germans from south and I would say that Bavarians have more in common with Austrians than with northern Germans. And in a same way northern Germans have probably more in common with Danes than with Bavarians or Austrians. So it's really hard to say what Germany is, historicaly it's, as it was said already, result of unification under Bismarck, but there are of course other things that are important beside history like langauge, culture, descent...

Anyway, as I pointed out already, I'm not a German and it's not really my problem, I'd say that it would be the best if Austrians decide in which state they want to live.
