Isaac Asimov - foundation series too far off to be prescient, robots future hampered by three laws of robotics not being really possible so prescience of those not very high.
Heinlein - lots of space travel, time travel, far future - does not seem very prescient.
Bradbury - major sci-fi martian chronicles, I don't think likely to be prescient.
Andre Norton - too far future to be prescient.
Ursula K. LeGuin - sci fi too far future to be prescient.
Phillip K. Dick - his artistic worldview was prescient, but that is to say he predicted a lot of the concerns of literature and pop culture in our present, but I don't think his worlds were prescient. You could also say LeGuin was prescient in the same way Dick was.
