BBC Studios, back in 2019, got the rights to do a TV adaptation of the 'Runestaff' series, which may still be in development (if it does happen let's all hope it's better than what they did to Pratchett's 'Watch') but haven't heard anything more on that. This might be someone shutting down competing licences, or not renewing them, ahead of this series.
Or not, who knows?
