Hmm... I think it went this way:
Steve was wandering around the 'net and found my thread on Nekochan
where I expressed my interest in the second-hand market on the Xserve line and he just pulled the plug on the whole thing, just to make the second hand market prices go through the roof when there's an upcoming shortage of new servers.
That, or we could have a situation like with SGI hardware where companies will throw out equipment which isn't manufactured anymore.
However, that's highly unlikely on the other hand since Apple is still here (and will be!) and there's Apple fanboys all over the planet which will work their way like locusts eating up whatever second-hand equipment they can reach.
