What is SUN's official upgrade policy?

[Dan Severance]

Can anyone comment on the probability that SUN will offer an upgrade to
the SparcStation 2 from a SparcStation 1.  I don't know if SS2's have even
been announced yet, but we are interested in being able to upgrade.  Can
SUN (or does SUN) comment on their policy in this regard?  I'd like to
know the official position on this matter...

    Thanks,
      Dan Severance
