Last I read was early 2025, Brust was saying that he had over half of the next-to-last book written, and as I said, he's been on a pretty regular schedule. Plus, he's not (only) telling a single story that has to come to some earth-shattering conclusion (as GRRM is). It would be nice if he pulled that off, but there is a lot going on in the background of his Dragaera that I expect he won't fully resolve: there are multiple types of death, multiple types of magic, Vlad is the reincarnation of an ancient Dragaeran, he's going to/has killed a god, the Jenoine are a mystery to resolve, and the whole planet has a science fictional foundation despite very clearly being fantasy in general.
But maybe he will; I'm actually several books behind at this point -- I'm pretty much waiting for him to finish so I can (re) read the whole thing from start to finish.
That was true for GRRM twenty years ago, but not today.
