Sun's running 4.2.

I just heard a rumor that Sun wouldn't be delivering 4.2bsd
until the fall... and yet they announced it a couple of months
ago (which is not really inconsistent: to announce all one
needs is a price).  It seems logical to me that if the 
Vax 4.2bsd isn't done then how can Sun's (since presumably
they will be very much alike)?  Are there any user sites
running 4.2 on their Sun's?  What is the real deliver schedule?
(Sun itself says they are delivering now, and of course they
are demoing 4.2, but who actually has it?)
