well after reading the date august 22 on the patch notes most people figured out its important
it says
Patch 27.2 is a massive patch, launching both Battlegrounds Season 5 and the first official Twist season, our first-ever direct-to-Wild expansion
and after that
On August 22, Battlegrounds Season 4 will end and Season 5 will begin.
thats how i figured out the date was the release date
what did you think it was ?
