It's worthwhile perusing Section VI of the "OS/2 Notebook" from
Microsoft Press (1990, ISBN 1-55615-316-3) that starts off on the
subject of OS/2 2.0 with an interview with Jim Cannavino and Bill
Gates.
It's not clear who was doing what, although Microsoft appeared to be
involved. Some quotes from Mr. G:
"Microsoft has not changed any of its plans for Windows. It is
obvious that we will not include things like threads and preemptive
multitasking in Windows."
"After mid-1990, Microsoft will ship PM versions of applications at
the same time or before Windows versions. We can see the opportunity
to create much better applications under OS/2."
"The goal for OS/2 is to be the universal operating system,
supporting every application ever done for DOS, the Macintosh, minis,
Unix and Windows."
"OS/2 is our top priority. We are still in boot-strap mode. We have
a very aggressive goal to sell one million units."
FWIW,
