Well, tastes are necessarily personal, but to me jazz is ever new. Miles Davis' last few records revolted many of his long-time fans and the jazz "purists", but they're the only stuff of his that I really like today. I doubt I'll live long enough to listen to enough Sun Ra so that I reach a point where the next record of his I hear (there are hundreds) is not full of surprises. The last of Coltrane's stuff is completely out of reach for me now, but in ten years who knows?
There are plenty of very good players today, but no wild-ass superstars that I know of. And there's a lot of tired crap. This is a problem. And while I've seen some very good players in Europe, if it comes to listing the absolute all-time greats of the genre I can only think of two non-Americans, Django Reinhardt and Stephane Grappelli, and their time was long ago (though I did get to see Stephane a couple of times and he was still quite "hot"). So if I was much younger, and especially if I was younger and lived somewhere other than America, I too might think that jazz was over.
But as some obese, drugged-up, weird-ass beatnik-turned-hippie once told me,
I recall your darkness
When it crackled like a thundercloud.
Don’t tell me this town ain’t got no heart
When I can hear it beat out loud!
