Just some info I found on the IL forums:

Along with 4 IKWF teams, the Top Dawgs will also be representing Illinois. Ohio also has 5 teams competing: Ohio USA, Ohio Lightning, Team Heffernan, and 2 from the Ohio Stallions. Indiana is sending a Gold and a Blue team. Nebraska is sending 2 teams as is newcomer Kansas. Filling out the field of 21 are Michigan, Kentucky, Tennessee and 1st time visitors to Danville, Wyoming and South Dakota.
