Yep. From early indications, they were making it a little “monster of the week”, which kept with the first collection of stories that start out the series. This trailer seems to deal at least partially with the through-plot that starts in the first collection of short stories, then carries through into the novels.
After the novels get going, there’s actually very little monster hunting, with an exception towards the end of the series. Ironically, in some of the books there’s even very little Witcher, as the story follows his adopted daughter more and more.
