QuesCan the admins chime in and let us know which teams are headed to main and which aren't?
They really can't right now for three reasons:
1. IM playoffs are still underway - we don't know which team is getting bumped up to Invite via winning the IM division.
2. Teams with standing IM rosters will die/reformat in the offseason.
3. Playoff Open teams need to decide whether they're going up or not - and not all of them are going to bring a new roster into IM.
There were about 7 IM teams that died mid-season. BIG BOYS just recently closed up shop and are not going to play next season under their roster. That means we have 17 remaining teams in IM. Let's say 15 of those 17 properly reformat or survive to S15. Now factor in that there will be about 1-3 teams that are cannibalized/called-up to fill out a 10 team Invite.
At this stage you're left with about 12-16 IM teams - and maybe 13 Open call-ups. There are a few ways Killing can draw the line here based on what we know now.
Both IM and Main are going to be very small, intimate divisions in which everybody knows everybody.
