Do you guys think they'll just tell when the championship will be? Or do you guys think they'll do something else aswell?

“Join us on May 28th for a stream focusing on X-Wing and Star Wars: Destiny™! Not only will we announce the dates of the 2019 World Championship for both games, but we're also giving you the opportunity to ask your burning questions about Organized Play. If you're a fan of either of these games, this is one stream you won't want to miss!”

If you mean spoilers, I doubt it.
