The updated tournament rules for the 2012 season are back online:
www.fantasyflightgames.com/ffg_content/coc/support/coc-Tournament%20Rules%20Ver%202.0.pdf
Notable highlights:
One 50-minute game per round.
The legal card sets now include the Forgotten Lore cycle and end with the Ancient Relics cycle. It appears that any APs from Revelations will not be tournament legal.
Notable mistake:
Under the Pre-Game Setup section detailing how to pick who goes first, the rules still talk about multiple matches per round. I'm considering some type of rule that randomizes the first player during the initial round, but then shifts to a non-random process in round 2 (and 4, etc) so players have a chance of going second at least once in the tournament.
