PAX game expo organizer Penny Arcade says it is expecting a sellout show with more than sixty thousand attendees at its first-ever East Coast event, reports Joystiq.  Penny Arcade’s Robert Khoo said the show, dubbed PAX East 2010, is expected to have more attendees than PAX 2009 in Seattle.  That show attracted nearly 61,000 attendees.  Joystiq says organizers are expected to announce this week that fewer than 1,000 full access badges for the three-day event remain.  The outlet also adds that those buying passes don’t seem deterred by the fact that speakers and sponsors have yet to be announced.  PAX East is scheduled for March 26-28 in Boston.  Read more at Joystiq.
