WBC, now in Lancaster PA, is another one. This year it will be part of the pre-con, running 3 games on Saturday Aug. 2nd starting at noon, the top 4 players then advance to Sunday 9am Semi-final, followed by a mutually agreed upon time for the Final possibly later on Sunday of the two finalists.
I believe it will be using the expansion and bidding Dwarven rings (action dice re-rolls). Though that won't be finalized till the end of January. (when I get my event description completed! lol)
