There's discussion going on for expanding to 32 teams and there's a good number of them in the top 32 who can be added in (/tech/, /r9k/, /mu/, etc.).
However there's been discussion about potentially having a format different from the other Cup and the one proposed would be a year-round event where 9 months is a round robin "Regular Season" where there's 2 conferences of 16 teams playing 16 inter-conference games and then the top 8 from each would go to Playoffs and those would be done some time in the 3 months of Summer (June, July, August) and would be like CL and have 2 games for each matchup and winner advances on aggregate.
However I'm hoping we can get everything sorted out within the next 3 weeks, promo content and streamers included, and then have a thread to discuss a new format so we're not just copycating someone else.
