No, as of right now, nothing mentioned at all.
As far as I know, what they are doing currently is focusing on a handful of smaller projects, and some other big project called ASCOT (you can even see some posters inside SoD) which appears to be some kind of fantasy action souls-like RPG. But it feels like it's in some kind of development hell, because I've been hearing about this game since 2018 and it still haven't released.
So while there hasn't been any mentions of SoD3 (for now), it's an easy bet to place that a sequel will eventually come. The SoD games are their most successful ones by far, and it would be a poor financial decision to not continue the series.
