Ok hypothetically what would happen if this happened.The German states become a third German country, that way we have Prussia, Austria and this other unnamed country.I imagine it would be a matter of who is in charge out of all of the states to run this new country?

Do you mean as a settlement? Who would run it would be a seriously big problem because the question comes in of who is Head of State. It would take foreign intervention to settle that, and there would still be internal disputes. Unless you want to abolish any semblance of monarchy in German State #3, but that has it's own issues.
