No State Machines in Windows Workflow 4.0?

After learning that Workflow Foundation 4.0 is likely to be missing StateMachineActivity, I think I’m going to hold off on any more research into lifecycle-of-OTC-derivative-as-Workflow, until 4.0 is released. Which is a shame, because in 3.5 I actually liked what I saw so far and was formulating some interesting posts on this.
