Apple unfortunately is your biggest hinderance here
not VMware.
Wrong. There is nothing to stop anyone creating a virtual machine product for the Mac. In fact someone did it a while back and it proved so popular, Microsoft bought it and now market it as Microsoft VirtualPC - and it is available for the Mac as well as your standard old Windows machines.
From the Mac virtual machine you can run yourself a copy of 98 or XP - even a Linux machine - although support for that is flakey at the mo...
So many future things are unknown such as Apple's
plans for virtualization, e.g. adopting Intel VT
chips, embedding a hypervisor, and OS X-x86 running
virtualized on Apple hardware so other OS's could run
as virtualized domain peers.
I am afraid this is just FUD. Head over to
http://developer.apple.com/ and take a look at the specs - the design, architecture and specification of the machines is all there for developers to ingest and get cracking with. Nothing Apple does between now and the Intel Mac launch is going to stop you from writing software for the platform.
Even as a straightforward App on OS X, Player
implementing all the features such as virtualized
device drivers, network bridging, etc is quite an
investment on an entirely new OS, which itself is
currently beta.
OS X is not in beta and it is not 'entirely new'. If you care to look at ADC and opendarwin you will see that ports for x86 have been around since year dot. Apple themselves have said that for every PPC OS X release, there has been an internal x86 build - the same in all respects.
Finally if Apple starts with its mini line as the
first x86 boxen it will be some time before a decent
install base of x86 customers exist to use Player.
Why? - no one should be developing for one platform only. If you are developing for the Mac you should be compiling and testing against the two platforms, PPC and x86. That is what the developer tools Apple provided are for. The base code for your app will be virtually identical - you just build for the right (ie BOTH!!) platforms.
So it doesn't matter if it is the mini, a powerbook or power machine that is first off the x86 rank - developers are building for both platforms. PPC will be supported until at least 2010... and x86 binaries will start appearing next year. Most people won't even notice the transition - which is how it should be.
Hope that clears up some of the FUD.
