First, technically, GenCon's bankruptcy situation has to do with issues stemming from their management of the Star Wars Celebration convention, which was on behalf of Lucas
film, not Lucas
Arts (which is Uncle George's computer-game company).
There's a big discussion of the topic over on the GenCon board. Someone posted there, yesterday, that he'd received an e-mail from WotC Customer Service, stating that WotC/RPGA had not yet submitted their events to GenCon, because they were waiting for "further proceedings" in GenCon's bankruptcy case before they'd submit their events. I have no idea if this is truth or fiction (no one else has provided similar info, and several posters on those boards are skeptical).
However, in that same thread, Dave Christ (the senior GM for the RPGA at big events like GenCon) posted:
Don't lump the RPGA (which is 100,000+ of us) into Wotc/Gencon/Hasbro or whatever large company is being 'Da Man' for the day. We're all just gamer goobs like everybody else just trying to do the best we can with the cards we're being dealt.
Trust me I would rather be starting up my judge recruitment and scheduling then typing these emails again and again in various places.
And, on the RPGA board itself, several folks involved with LFR indicated that they'd given the information for the LFR events to WotC to pass on to GenCon. If that's the case, then either (a) WotC is sitting on the information (which makes the above story seem plausible), or (b) GenCon hasn't processed the information (seems unlikely, given that they claim they're updating the event schedule daily).
I also note that GenCon scooted event registration up by several weeks. I wonder if this was done to improve their cash flow situation (i.e., get several thousand people's event fees in GC's pocket a few weeks earlier).
