Winners of each division are the top two seeds. The top team out of the remaining gets the third seed. The fourth and fifth best remaining teams play a 7-game wild card series for the fourth seed slot. Then playoffs continue as normal with play-in winners playing against top seed. So effectively, were the season to end today in the East we would have Buffalo as top seed, West Kendall as second seed facing Hamilton as the third. And we would have Chicago vs. Manhattan in a 7-game series to determine who faces Buffalo.

EDIT: The more interesting one is the West where:
Los Angeles would be top seed as division winner, Minnesota despite being 4th would be 2nd seed as division winner. New Orleans would be the third seed, playing against Minnesota. San Francisco and Calgary would have the 7-game series to decide who faces LA.
