Yes, the evolution might be nondeterministic. I am intentionally not saying much about the details, just that one state gets mapped to a next state. Before one can really think about the properties of the evolution one has to think about the properties of the state and I have no idea what it would look like. Is it a classical state, is it some quantum-mechanical state, is it an infinite collection of substates for each universe in a multiverse?
