NCAA Div. 1 and CJHL would be great added to NHL 24, but 63 NCAA Division 1 teams has been shared to seven divisions (Atlantic Hockey, Big Ten, CCHA, ECAC, Hockey East, NCHC and Independent). In CJHL is 118 team and these teams has been shared 9 different leagues. I think, that EA Sports won't start adding 181new teams to game.
