Ubisoft has staked its claim on a time and place for its E3 press conference this year. It will take place at the Orpheum Theater in Los Angeles on June 11 at 1 PM PT. The company will also host a live pre-show and post-show to couch the event.

We know that this year's show will serve as the coming out party for The Division 2. Ubisoft announced the sequel with very few details and promised more to come at E3. Also around that time, the first game, The Division, will be updated with a new Crests system, which unlocks rewards in the sequel. It wouldn't be surprising to see these plans outlined at the show to encourage players to jump back into the original.
