When I submitted the story maybe 8 hours[1] after the announcement, it was already out of stock. This person says it sold out in 1 second - https://x.com/henry19840301/status/2090652363434647738 - if that's possible.
One can sign up for new product releases and if I paid attention to my marketing emails I could have clicked through. I'm guessing there are enough people who do combined with limited initial stock. We don't know.
Thanks for passing through the info for those of us not on Twitter!
