Hello,
"You perport to know the very details of when OS4 will be available"
You don't need to know exactly what is going on at Hyperion to see that OS 4 can't be available for March 2003.
It's just a matter of rationality and a bit of software development experience or observations.
As i've already said in a previous post, but you must have not read it, all the other OSes on the planet had a full builds betatesting period of at least 6 months and most of the time it's 1 year.
Full build betatesting means betatesting of completely built OS (also known as final betatests) so this happen AFTER betatesting of each elements by themselves.
As i've already said, OS X 10.2 (codenamed Jaguar) which is only an update for OS X 10.1 (Puma) had an external (so made by external people, and so after the internal betatests) final betatesting period of 1 year (again final betatesting == complete build betatesting). And it's just an update for OS X 10.1, which is nothing in term of work compared to OS 4.
As OS 4 is also an OS and so also a software it'll also need external final betatests.
Don't tell me this has already started, as at the WOA SE no complete build were ready yet and even if there is one now, that would mean we have to wait 6 months or 1 year before the consumer release if we consider they start the external final betatesting know.
And you don't need to be very good in maths to see that today+6months (at least) does not equal to March 2003

As you can see, here I just used real facts from the industry and from the official status of OS 4 at the WOA SE show. I've not used any kind of things that are not real facts.
So here it's not a prediction of the future, it's just using verified facts to make you realize that there is some things in the life that are simply not reasonnably possible. Or maybe OS 4 Team is so good that they can even be better than any other developpers team in the past?
I don't think so

Regards
