I think they'll start fighting in groups and each individual will get ranked, similar to the BFE's rankings for each level of Gold. It doesn't have to be an exact scientific ranking, just rough levels of skill or power level for seeding purposes.

The real problem will be how do you whittle down 96 participants (8 factions * 4 teams * 3 participants = 96) to about 32 or so. I guess probably the top 32 ranked fighters would get a bye, and the bottom 64 would fight 1 vs. 1 based on seeds with the winners advancing and getting re-seeded and matched up bottom 32 (half of the bottom 64) vs. top 32. So that's the ro64, then ro32, then ro16, etc., etc.

That's just my guess.
