its obvious that the final event will either be in like florida, georgia, or south carolina. its going to be october. they aren't going to have it in the northeast, there are already 2 events (dc and boston) up there.
they already stated previously that there would be an eastern and wester conference with 6 events total and 3 events counting towards each conference. as of now there are 3 confirmed on the west coast, 2 for the east, and the final one is unknown. by using basic logic it makes it clear that the final event will be east coast to keep the conferences equal. where exactly on the east, we dunno, but my guess is that it will be in florida somewhere, possibly atlanta.
