Afaik they have a limited staff when it comes to STO lore. Kestrel said himself/herself that he/she is currently working on in-game lore, so that he/she can't work on the Path to 2409. I'd be willing to bet that this is the same with the ship listing for whoever does those.
I personally think it's more so that the web team is slow. They already have the page for the Vigilant and Excalibur done, yet neither is posted (I know this because the Vigilant video is up on video websites and the Excalibur page was hidden on the site without a link to it for over a month). Typically, games have the webpages done by launch, so we can hope it will be added before Tuesday.
