The ending hints that Emhyr has some kind of large monster, specifically a flying one (and likely a griffin from the shadow we see of its beak), that will track down Geralt. One of the first things that happens in W3 is that you fight a Griffin.
Most likely I'm insane for even suggesting this, but that felt like a hint that we might get a condensed/adapted Wild Hunt arc for season 5, maybe spliced in with the Vilgefortz story.
Why is this improbable? Destroy my hopes, please

Who else wants to see more of the Witcher universe on Netflix past the Witcher season 5?
I can't wait for Season 5
2019 fantasy drama television series
Please don’t hate on others opinions
Also I don’t care how likely or unlikely you think it is to happen just if you want it or not
In my opinion this season by far had the best action than any other seasons. This Geralt I like way more. I'm not a book reader so I can't compare to the books, and complain how everybody else been complaining. To me season 4 was one of the best seasons.
P.S I can't wait for Geralt to find that weird old Witcher killer
