Since you seem to be able to communicate freely with Bill, could you please ask him these questions and relay the answers back? I think the answers will clear up most of the questions we have and should not break any NDAs:
Regarding OS5, will I be able to:
1. Take source code for any OS-legal AmigaOS 3.x program (ie a program that follows the guidelines in the Amiga 2.x/3.x programming manuals), compile it with the appropriate tools and expect it to work?
2. Take an OS-legal AmigaOS 3.x program from Aminet and have a reasonable expectation of it working?
These two questions will tell us all we really want to know about OS5 (source and binary level compatibility). Anything else is just details.
