A month ago I was hearing several people telling me that MacOS 8 (Copland)
will be only available for PowerPC based machines..  I just checked out
the Apple website for OS 8
(http://www.macos.apple.com/macos8/overview/qa.html) Q&A page and under
system requirements the only thing mentioned is a minimum of 8 megs.

So, is this rumor I've heard about Copland not running on anything other
than PPC just a myth?

No, the rumor you've heard is not a myth.  Mac OS 8 is being designed to
be an PowerPC operating system because this allows it to take full
advantage of the the PowerPC RISC architecture. While it would be possible
to program Mac OS 8�s actual software for a 680x0-based system, many
features (such as the PowerPC-optimized code) would not provide any
benefit to 680x0 users.  However, Apple does plan to continue supporting
System 7.5 for the 680x0-based models.

Yes, you're right that Mac OS 8 will not run on 68040's which were
upgraded to PowerPC.  This is because PowerPC-based Macintosh computers
are architecturally different from Macintosh systems with a Motorola 680x0
processor. Apple has made PowerPC upgrades available for several Mac
models but upgrading the processor does not change the system's inherent
design.  Again, Apple does plan to continue supporting System 7.5 for
these models.
