I don´t think like you, without the ICLM, Peugeot or Audi wouldn´t be on LMS or ALMS races this year (mostly Audi), their partial presence gives more streng to both championships.
We´ll have about 6 races next year, if the ACO makes mandatory for the teams run in 8 or 9 races the regional championships won´t loose anything
BTW, There are more teams confirmoed for the international series?
