The recording of the webcast is available at: http://www.appeon.com/recordings The following is my summary of what was discussed.
SAP Agreement is Final
The agreement between SAP and Appeon was finally made official on July 5th. A "new generation" of PowerBuilder is planned for release in 1H 2017.
Multi step process before new version can be released
1. Setting up development environment
2. Knowledge transfer from SAP
3. Missing pieces
PowerBuilder uses some third party technology that SAP may not be able to transfer rights to or which may no longer be available. In either case, engineering effort will be required to replace the technology.
4. Add new features
5. Convert to new licensing system
