Today they released the Launch Guide and made the game available to pre-download.
Launch is 8am Pacific Daylight Time (PDT) on Thurs Sept 23, 2021. We FINALLY got a new map which will help those who want to adjust for their time zone. Please watch the international date line. Please click here for time zone assistance.
Lots of other info is available here - including info for Consoles.
If anyone has other questions, needs help with how to purchase, install, or time zones please ask.
