The official E3 2010 website has put live a list of its currently confirmed exhibitors.
It's a line-up that ticks off the big publishers as expected - Activision, Bethesda, Capcom, EA and Ubisoft are all listed, as are the three platform holders. More companies will be added as they are confirmed.
The event is still five months away, to be held at the Los Angeles Convention Center on June 15-17.
Early bird registration to E3 is available until May 3, with the price of the Expo pass rising thereafter.
Full details can be found at the event's official site.
