I spoke to Guptil on the Top 8 issue at the event and he said he would take it into consideration for next year's Origins scheduling. He gave me many reasons why they don't run Top 8's @ Origins, but the biggest one is scheduling/judging cost... it *does* cost 50% more to judge a 6+3 round tourney than simply a 6. *shrug*
Want to help out? Play in as many of the GenCon tournies with Top 8's as you can, so that PES sees the profitability of it!
