alright so pipher replied http://cevo.com/forums/topic/6284/team-fortress-2/questions-for-cevo-regarding-tf2/
tl;dr version:
-they might have ddos protection on their servers, they might not
-no guarantee on getting a reschedule if ddos'ed, case by case basis (they like to think they're fair about it)
-they should be able to roughly triple the prize pool of this season so no increase in fees next season even with new divisions
-cevo-p "more than likely" to be in next season, another division (im/main/whatever they call it) as well if participation increases
-increased prize pots (no defined amount) and prestige to tempt teams to play in the highest possible divisions/not sandbag
-you can file a formal dispute if you think someone's cheating (tf2 staff--no clue who--reviews a demo or something?)
-supposedly paladin ring0/kernel cheat proof
