Hello,
I would be happy to help. 
For the actual release of any BnB videos themselves, you might want to check in with BoardsandBeyond themselves, as we don’t have a ton of insight there as to specific dates for which they plan to release particular videos.
As for timeline on updating tags for new videos as they roll out we unfortunately don’t have a specific timeframe that I can quote for you, sorry to say. It depends on when they release them, when they release other tagging-specific information to us, availability of maintainers, a handful of other things.
As a very loose goal, maybe a couple of weeks but that may be aspirational as much as anything.
If you have interest in becoming a maintainer you are welcome to apply. More information can be found here: 📚 AnKing Step Deck Submission Guidelines
Please let me know if that answers your question, and if there’s anything else I can help with.
