California Extreme 2011 [http://caextreme.org/] took place on July 9-10 this year. Near as I can tell, the exhibition went by unnoticed by Escapists.
Basically, they reserve an exhibit hall in the Santa Clara County Convention Center for a weekend, fill it with arcade machines, set them all on free play, and sell tickets.
This year they had to turn some machines away because they had maxed out available power to the hall.
I shot a walk-around video on Saturday night/Sunday morning, which should give you a vague idea of what awaits you when you visit. (This is my video; there are plenty of others on YouTube.)
