This looks like an announcement of an announcement, which isn't on topic for HN. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...
On HN, there's no harm in waiting for the actual thing: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...
The way I've understood the "announcement of an announcement" rule in the past is that it is for reports/rumors that somebody is company to release something, or a company sending a teaser for a future event where they'll announce something.
The standard has never been that the product needs to already be generally available to be on-topic. If that were the standard, when could we discuss say a new iPhone? Not when it's talked about on the big Apple stage. Or as another example consider yesterday's discussion of the changes to the Google account deletion policy. No accounts will be deleted for 9 months, was it an announcement of an announcement?
The comments in this thread are nearly entirely generic, though.
