The show 1899 has been canceled by Netflix after just one season: https://www.whats-on-netflix.com/news/1899-canceled-at-netflix-why-season-2-isnt-moving-forward/

Will a second season be announced before the 1st of July 2023?

Question resolves 'yes' if an anncouncement is made by the show's creators (Bo & Jantje).

This could be because Netflix changes their mind, or because a different streaming service or network picks up 1899.

I'm not sure what the base rate here is, probably very low. I know Brooklyn 99 once got canceled by Fox and picked up by NBC, so it might be possible. I won't participate in market.
