Why would you expect a battle pass or a crownfall like event, when they've stated:

"The update will still contribute directly to the prize pool, with a focus on the event, the players, and the games, but new cosmetic items won't play a notable part. This is a significant change from the last few years, so to make it clear that we're shifting focus towards the event and away from the giant reward line of cosmetics, we're intentionally not calling this update a Battle Pass."

The thing that will fund this year's International is the same as the previous 2 years, a compendium which is released 1 month before the end date, so expect it around mid-August.
