Any information on timelines for these?

Specifically "40.8% market share for new product licenses shipped in
1997" -- that's a unit count, not a sales dollar volume, metric.  I
suspect that the dollar sales represent at best a very small share of
the market.  Revenues for 4Q1997 (presumably based on similar shipping
vlume) were $57m.  The same press release also announces a "partnership
with IBM", presumably Project Monterey, to "jointly develop and deliver
a UNIX operating system family that works on Intel and IBM

The actual announcement was Oct 28, 1998:

Anyone got actual unit shipment numbers for SCO?

...and the presence of other x86 Unices is acknowledged directly here,
with a head-to-head against Solaris on identical x86 iron:

   SANTA CRUZ, CA (September 9, 1998) - SCO announced today that its
   UnixWare operating system dominated AIM Technology's Hot Iron Awards,
   which were held on Tuesday, September 8, 1998 at the Palace Hotel in
   San Francisco, California.
