It's pretty certain that they won't even support Classic on the

The emulators around now all work best on ppc, no surprise there -
much faster. Classic support will suffer alittle, there is alot for
apple to draw on and Rosetta must go a fair distance to do whats
claimed which should be good for emulation over all.
Rosetta doesn't emulate the hardware down to the devices, it works in
cooperation with the application, switching out of the emulation at
the system call and possibly framework level. You won't be able to
boot OS 9.2.2 under it, so you won't be able to run Classic
applications on OS X86 at all:
In http://developer.apple.com/documentation/MacOSX/Conceptual/
universal_binary/universal_binary_exec_a/chapter_7_section_2.html -
Rosetta does not run the following:
* Applications built for Mac OS 8 or 9
* The Classic environment
* Code written specifically for AltiVec
* Code that inserts preferences in the System Preferences pane
* Applications that require a G4 or G5 processor
* Applications that depend on one or more kernel extensions
* Kernel extensions
* Bundled Java applications or Java applications with JNI
libraries that can't be translated
Sorry, I guess we should hope Apple doesn't come down to hard on the
current *free* emulators.
I had only read or remembered the
Rosetta is designed to translate currently shipping applications that
run on a PowerPC with a G3 processor
bit from the coverage of Jobs speech.
AltiVec is currently early alpha as far as current Pearpc x86 emulation,
not pretty.
The "Classic environment" will now be SheepShaver for 7.5 -9.1, Basilisk
II for 68k OS7 - 8.1 and Vmac(mini) for the list. Basilisk II and Vmac
work well on intel, SheepShaver (ShapeShifter) is coming along nicely.
There are some good small time programmers working on and porting the
CVS of these three emulators to OSX, I'm sure this will continue. You
will need a copy of your roms. I dont think you should pay again for
these and the current system works well enough, making older versions of
the os free and limiting the availablity of roms which Apple, I guess,
does well at the moment.
I'm surprised at the apparent lack of Apple support for the Classic
environment. There are other ways to skin a cat, they currently work
well on x86 and will only improve.
