Prior to the start of the season, Nijmegen Devils announced a one-year hiatus from the North Sea Cup for 2011-2012.
An expansion team known as the "Amsterdam Capitals" joined the league, with many of the same people as the defunct Amstel Tijgers of the Dutch Eredivisie.
At the end of the season, the Leuven Chiefs announced that they, too, were leaving the North Sea Cup tournament.
The North Sea Cup was therefore disbanded and the last remaining Belgian team, HYC Herentals, was admitted as a full member of the "Eredivisie" Dutch league for the 2012-2013 season.
HYS The Hague edged out Geleen Eaters on goal differential to win the North Sea Cup tournament, as both teams attained 36 points.
