Based on Minecraft tweets, and current pre-releases and betas, 1.19 will come at June 7, with unknown timezone yet.

For the PH Side, update is expected to be released on June 8.

The update will get supported ASAP because Mojang is serving the 1.19 BDS by the time as I’m writing this.

Some updates that are expected:

• XP Glitch is patched
  (we refused to update on 1.18.33 until next update releases as it does not impose security vulnerability)\
• Ancient Cities, Warden
• Swamp, Frogs, Mud Blocks
• Goat Horn
• Allay
  (Minecraft Live 2021 Mob Vote Winner)
• Chest Boats
• Disc Fragments
• and more…
  (Please check 1.19.0 Beta Minecraft BE Changelogs)
  
  We’ll update it for more information
