The policy at the time (1983) was to release externally one release behind the current internal release. That changed with UNIX 5.0 which was released internally and externally at the same time, becoming System V. Then the marketing people got involved, and didn't want System VI as the next release, so they went to System V Release 2, 3, and 4. As to previewing your talk, why not?
