The following is all part of the "Summer Update" status / news:
ADDITIONAL ENHANCEMENTS
And in addition to these roles, the next update will also deliver a variety of new content and improvements aimed at enhancing all your experiences inside the world of Red Dead Online, whether within roles, competitive modes or simply exploring free roam.
Substantial, across the board changes are being made to combat and movement to allow for a more responsive control system that still feels natural. Additional damage reduction to Defensive players is also on the horizon, and the game will now remember your preferred playing style (Offensive or Defensive) when you exit and relaunch the game. There will also be many more lootable items to be found throughout the world, like containers on wagons or the occasional Gold Tooth on an unfortunate soul.
The next Red Dead Online update with also feature the ability to reset your character’s appearance and much, much more.
Stay tuned for more details to come and check back for new weekly events in Red Dead Online.
When they say the "next update", I think it's clear they are referring to the Summer Update. The excerpt above is a description of what is supposed to come in the Summer Update.
These content drops seem to be settling into a seasonal schedule. The Spring update was mid May and the Summer Update seems set to release sometime before Fall begins (late-Sept). My guess is in the next week or two but that's just an assumption.
