I don't know either, but from what I can see, it is seems pretty obvious that OCD is just a side project. Nothing wrong about it, but projects that are main source of income have much more dynamics, like Collectorz to name something similar. Also, projects that charge for upgrades seem to move forward at a faster pace.
My bottom line is, if neither of above changes (nor Andrei has just more fun/income of developing/maintaining OCD), not much will change, including developing multiple-years standing fixes/requests.
