At the risk of raising expectations that may be crushed what is still official over on steam is Community Update 20 which states the following verbatim:

"The Collector’s Edition should make it to you around the 31st of August, the original release date. For those who ordered on PC, your Steam code will be emailed to you earlier so you can start playing sooner. (Quick note: save games will not transfer from your Early Access build to release, but within the 72-hour period prior to launch, they will).

On PlayStation 5, to ensure you’re ready for your Digital Deluxe Edition 72-hour Early Access period, your code will be sent to you via email before the 72-hour period starts, so you can jump in right on time to claim your rewards. Phew!

You can still buy the Collector’s Edition over on the official website, ce.baldursgate3.game. It’s ma-hoosive. We’ll show you at the Panel From Hell: Release Showcase."

Hopefully we will get clearer word on this tiday.
