Yep. There's 6A now-- made up of the six schools with the most male students and all of the schools were scheduled to be in the 6A playoffs but Presbyterian Christian was disqualified from the playoffs. They had appealed but the ruling went against them and now the 6A bracket has five teams in it.
Edit to add: 6A is a football classification only. All other sports go up to 5A.
There are 6 football-playing schools in 6A, 17 in 5A, 15 in 4A, 17 in 3A, 16 in 2A, and 12 in 1A.
There are 2 schools in 4A that don't play football (Laurel Christian and Macon Road Baptist of Tennessee). River Oaks of Monroe, La., another 4A school is planning to apply to the LHSAA which means that will likely be 14 schools playing football in that classification next year.
