On a related note: Is there any statement from MAXON on the future of the old xpresso-style node system?
We are looking to implement a node-system in our plugin, and since API for the new node system is not out yet we may consider using the legacy xpresso API instead. On the other hand, it would not be a good idea to invest resources in this if that part of the SDK might be deprecated and replaced with the new node system.
I realize that you may not be able to provide much info on the roadmap here, but any information that you can give would be super helpful for making this decision!
