Surely they wouldn't call a press conference if they aren't even sure what/if will be done today. I mean, to call a press conference has to mean that they have reached an agreement, and today just formalizes that by an official vote. Right? Right?
What will happen is one of three things:
1) They will choose to expand by 2-4 teams
2) They will chose not to expand at all
3) They will delay the announcement
I don't think they will say specific teams today. I think they will agree to expand. I think they will agree to do it by two teams. And they will decide today. But that specific announcement won't be made today. Only the announcement to expand.
