Has Shopify announced when these will be released for the public? They announced them at the beginning of the year, and from my understanding, stuff announced is typically released at the next editions, which just happened.
Thank you.

Not how that works at all.
Theme blocks are in developer-preview status for the foreseeable future.
If you need access use the developer previews or join the reference themes discussions or the OS3.0 channel in the partner slack.
