Ok, thanks for the clarification!

PowerPC was chosen for a few reasons:

1)  Availibility of 68k to PowerPC porting tools (originally for Mac,
but easily adapted for the Amiga)

2) Bus design is similar, allowing for PowerPC accelerator cards for
legacy machines (again, the reason for this was due to the Macintosh,
to allow Apple to make new machines quicker)

3)  Familiarity of coders with the work needed to port 68k to PowerPC.
 (yet another thing inherited from Apple's identical move)

4)  Ease of creating emulators to execute 68k code on the PowerPC
(bingo, Apple again)

So, in short, the decision was made because Apple did it, which paved
the way to simplify the work for the Amiga.  The tools, design
knowledge needed, etc were all created for the Macintosh transition,
which then Amiga could take advantage of for low-cost.  To port the
system to x86, even a limited setup, would have required a whole new
batch of tools and training developers from scratch.  Cost much more
in the short turn with the same chance of failure with either route.


Some people can proclaim cost savings with x86, but that's only with 1
component, the motherboard.  Otherwise, these systems are the same,
same video cards, same networking cards, same hard drives, etc.

So you're not gaining much from this x86 plan, but instead gaining
huge debts in the development cycle while reducing your ability to
make money in the longer term...

No thank you, I think PPC is the way to go.

Actually it's MorphOS with the Hardware Abstraction Layer, as
Hyperion/Eyetech have opted to use uBoot as their booting mechanism
rather than the industry HAL called OpenFirmware.

However, HAL covers the peripherals, not the CPU.  To be cross-CPU,
you need a virtual processor, which brings up AmigaDE, Java, Forth,
Lisp, Ada, Squeak, Smalltalk, Rebol, Pascal...
