PI and old Wonderware Historian?

What are the plans with OSI PI and the traditional Wonderware Historian? Will an upgrade path exist to go to PI? Scripting to convert? Or will the 2 remain separetly offerings?  I still remember the very first release of the Wonderware Historian that had an option to import Citect as it was picked up from a 3rd party Australia and the Data Works purchase of the client tools?
