What OSes are "official" UNIXes? And what is their future? How about A/UX's future? And what is the future is of BSD (other then OS X?) IMHO's, sound off!
Today, the definition of UNIX ® takes the form of the worldwide Single UNIX Specification integrating X/Open Company's XPG4, IEEE's POSIX Standards and ISO C. Through continual evolution, the Single UNIX Specification is the defacto and dejure standard definition for the UNIX system application programming interfaces. As the owner of the UNIX trademark, The Open Group has separated the UNIX trademark from any actual code stream itself, thus allowing multiple implementations. Since the introduction of the Single UNIX Specification, there has been a single, open, consensus specification that defines the requirements for a conformant UNIX system.

COMPAQ: Tru64? UNIX® V5.1A or later running on Compaq AlphaStations and Compaq AlphaServers
FUJITSU: Solaris? 8 Operating Environment on SPARC®-based Platforms, 32-bit and 64-bit
IBM: Systems using PowerPC? architecture based processors with AIX 5L? for Power V5.2 or later
IBM: Systems using POWER? or PowerPC? architecture based processors with AIX 5L? for POWER V5.1 dated 9-2001 or later
IBM: Systems using Power? or PowerPC? architecture based processors with AIX® Version 4, Release 3 dated 10-2000 or later and IBM VAC Version 5.0.1 or later
SUN: Solaris? Express 05/03 Operating Environment, SPARC Platform Edition, 05/03 and on, on 32-bit and 64-bit SPARC systems
SUN: Solaris? Express 05/03 Operating Environment, X86 Platform Edition, 05/03 and on, on 32-bit X86 based systems
SUN: Solaris 9 12/02 X86 Platform Edition and later on 32-bit X86 based systems
SUN: Solaris 9 and on (SPARC 32-bit and 64-bit Platform Editions)
SUN: Solaris 8 and on, on 32-bit and 64-bit SPARC based systems
SUN: Solaris 8 and on, on X86 based systems
SUN: Solaris 7 and on, on 32-bit and 64-bit SPARC based systems
SUN: Solaris 7 and on, on X86 based systems
What does this mean? It means that "official" Unix OSes are Tru64, AIX and Solaris.
For the home user, anything Linux derived or BSD derived (including Mac OS X) is a "Unix-Like OS".
