But there is no way we could know what that predestined behavior is so we
would still feel free, we would still have free will.

Von Neumann was a very great mathematician, I don't think the man was capable
of making a mathematical blunder even if he wanted to, however Von Neumann
was not a great physicists, his mistake was physical not mathematical.
At any rate, I don't think the question of determinism has much to do with
free will because even if the universe is completely deterministic (and I
doubt that it is) it would still not be predictable, and I'm not just talking
about practical concerns and chaos theory.

I agree, and Turing's work may be even better, he proved that no computer
program (and I think that's what we are) can predict what it will do next,
that is, if it will ever stop. The easiest, indeed the only way to know what
a computer program will do is to run it and see, we figure out what we are
going to do when we actually do it. This would be true regardless of whether
the Universe is deterministic or not.
