This year, the Star Wars Celebration fan event will be the last one until 2019. Meaning 2018 will not have one, according to Lucasfilm on Celebration's website.
"The next official Celebration is slated for a location and date soon-to-be announced, in 2019," read a statement from Inside the Magic.
The Star Wars Celebration event began in 1999 to celebrate the launch of Star Wars Episode I: The Phantom Menace. When it first started, the events were not on a set schedule but would happen with the release of the following movies. But today, new installments come out every year and this has bolstered the event into a mostly yearly event. But they've announced that there is not an event in 2018.
This year's celebration takes place April 13-16 in Orlando, Florida. It's also likely that this is when Lucasfilm will release the first trailer for The Last Jedi. Plenty of staff, including Writer-Director Rian Johnson and Lucasfilm president Kathleen Kennedy, will appear on panels to talk about Star Wars and the new film specifically.
There's also news of a number of new Star Wars games, including Battlefront 2 and another unnamed entry.
