Last years master state bracket looked like this:
District 1 - First
District 2 - Fourth
District 4 - Second
District 3 - Third
District 4 - Third
District 3 - Second
District 1 - Fourth
District 2 - First
District 3 - First
District 4 - Fourth
District 2 - Second
District 1 - Third
District 2 - Third
District 1 - Second
District 3 - Fourth
District 4 - First
So it appears that this year's bracket would be as follows:
District 1 - First
District 3 - Fourth
District 4 - Second
District 2 - Third
District 4 - Third
District 2 - Second
District 1 - Fourth
District 3 - First
District 2 - First
District 4 - Fourth
District 3 - Second
District 1 - Third
District 3 - Third
District 1 - Second
District 2 - Fourth
District 4 - First
It could be that the seconds and thirds are reversed within the brackets, however, I'm not certain.

Maybe, Mike can confirm or correct this.
