Yes, I heard the news too, and can't be too surprised. The whole sedan market is tanking (the Cadenza's going kaput too), and the K was always in a somewhat strange little niche of it.
I hope to continue to enjoy mine for years. Since the Tau V8 went in things like the Borrego and Genesis as well, I'd expect engine and drive line parts to continue to be available for a good period of time. Body parts and other unique pieces may not be, but, all life is a gamble.
RIP K (at least in the US)!
