Mizerie has posted on the AML forums explaining how this season's seeding rounds are going to work. You can read what he said here.
It's pretty much the same as last season. The two divisions merge into one big ladder and we play two games. The only difference to last season is there's one less round. Personally I'd like to see the seeding rounds stay at three games as this gives more movement up and down the ladder and more chances for squads to make the top eight and move onto the playoffs. Also ten rounds in total (seven division games and three seeding rounds) is a good length for a regular season.
