Here is my reasoning:
At Spring COMDEX (May 24-27) Microsoft will "officially"
release/introduce/announce/whatever Windows NT.
Microsoft will by hyping Windows NT as the second coming of Christ,
but the best Bill Gates will be able to tell all the e*d people
is "before August 1, and this time I mean it".
Windows NT will be talked about *everywhere* because it is being
"released">
IBM & OS/2, since they are the underdogs, must not only also hype up
OS/2 2.1 as the greatest OS in the world, but they *MUST* also have
a solid, bug-free OS/2 2.1 available for people to HAVE. They must
have many IBM PC's and *clones* running OS/2 2.1.
It will greatly help OS/2's cause for people to be able to take it home
and actually have a copy in their hands at Comdex(not to mention magazines
and such will be able to review it sooner than they will the release of NT),
while no one will be able to get the GA copy of Windows NT v1.0 for a few
more months.
I don't know if IBM has the documentation done, but I figure that even if
OS/2 2.1 goes gold a week before COMDEX, IBM would be able to create
several thousand copies of the 2.1 package, on CD-ROM if nothing else,
and have it available at COMDEX.
Obviously, making OS/2 2.1 is *SOLID* product is the #1 concern, but this is
a best-case scenario.
Of course, I personally believe that Windows NT will be a big disappointment
to most. I mean, when NT is released to the public, it will be the very
FIRST time it will be available!
What v1.0 programs, much less *operating systems* were useable at v1.0?
DOS took until v5.0 before it was "ready for everyone"(maybe 3.3, but you
have to skip v4), Windows took until v3.1, OS/2 is going to take until
v2.1.
