I'll be there, with the rest of the Robotoki team on Thursday (13th) But it be awesome if we could get a small polycount gathering like we do during GDC.
List of the public afterparties. Maybe take a look at that list of events, make one our own? http://www.pocketgamer.biz/r/PG.Biz/PocketGamer.biz/news.asp?c=51164 I know a few Aussie Polycounters will be at the Surprise Attack Event.
I'm heading over with the CCP crowd this year for my first ever E3! Beyond excited! Would really like to meet the polycount guys for some pints so if you can get something booked I'll be there for sure.
As an LA native I know of a few bars near the convention center that people might be able to hang out at. Last year there was a gamedev meetup at the Golden Gopher. I am down to hang with some fellow Polycounters. - D. Carmine
