The classical physics view is a continuum of states from the past
to the future.  I don't see that you are saying anything different.
Is discrete change versus continuous change what you are interested in?
 
Scott Aaronson quote:

"For almost a century, quantum mechanics was like
a Kabbalistic secret that God revealed to Bohr, Bohr
revealed to the physicists, and the physicists revealed (clearly) to
no one. So long as the lasers and transistors worked, the rest of us
shrugged at all the talk of complementarity and wave-particle duality,
taking for granted that we'd never understand, or need to understand,
what such things actually meant. But today - largely because of
quantum computing - the Schrodinger's cat is out of the bag, and all
of us are being forced to confront the exponential Beast that lurks
inside our current picture of the world."
 
I am no fan of Bohr to be certain.  I do not believe a correct 
understanding of QM involves the kind of indeterminism or
involvement of mysterious processes Bohr wanted to believe.
