Via slashfilm.com:
Whether or not you’re in Anaheim next weekend for Star Wars Celebration, you’d better be on alert. We know that at 10 a.m. April 16, J.J. Abrams and Kathleen Kennedy will take the stage at the event to premiere the second trailer for Star Wars: The Force Awakens. That event will be simulcast in various rooms around that convention and, possibly, in cinemas all over the world. (That last part is still only a rumor, however.)
Word now has it that the duo will also debut the first Star Wars: The Force Awakens poster at the event.
