I'm not sure. I'd really like to get revenge on dPaladin and goldenkrnboi, so at this stage of the game I'm all for it. (although, with my luck, we'd have a finals system and I'd get the first seed, then get summarily destroyed in the playoffs).
The benefit I wasn't aware of until the AG tournament was adamant about HAVING a finals system was that we could almost completely eradicate the reporting system with finals. Since the ultimate goal is to find a single winner, the top 4 or 6 players in the round-robin will certainly have the best player (who actually shows up), regardless of reports.
I'm going to be looking to codify rules with Mew, Arek, and EasyP so that we can have a fairly uniform set of rules in place for finals. Since the four of us are the heads of tournaments, it'd be nice to use the same guidelines for all of them (or at least most - chess doesn't have quite the grand appeal that AG and EMU have gained so rapidly). PRC and ORC used to have the same voting guidelines and staggered their schedules pretty well until someone fucked it all up back in 2005.
Of course, that someone was me, but you live and you learn. Then you get Luvs.
