Anyway, my understanding is that there are often regional events that lead up to the world championship at GENCON. I'm planning to attend GENCON this year, is a similar tournament style event planned again for this year? If so where can we find out more information on regionals and what not.
No. This year, there are "rolling Regionals," for lack of a better term. A venue can sign up to host a Regional any time over the course of the year instead of just in the 6-8 week period from April through May.
There have been 2 so far (sort of). The first one was in Iowa back in October, but it ended up not being a true Regional because not enough people were in attendance (and the Regional kit showed up a week late). The other one was the "Black Friday" event in NYC the day after Christmas.
Other than those, I haven't heard of anyone even entertaining the thought of hosting one since the Organized Play program announced the "LCG only" as the primary Gencon tournament format. rings may be thinking of getting Regional status for Kublacon, but if he is, he hasn't mentioned it on the boards.
