Have you all ever considered that you have to optimize the code for a new CPU?
What makes you suggest that the code would be particulary "un-optimized"?

In the days the Pentium IV 1.4GHz pops up, it was as fast as a Pentium III 1GHz.
Those were AFAIK two different microarchitectures, and while the "Netburst" architecture might have had its upsides, it also had certain issues. It's telling that Intel went back to an evolved version of Pentium III's "P6" architecture (the Pentium M) for their "Core" CPU's that came later.

The same with the G5s ... at the early days a G4 2GHz was "nearly" as fast as a G5 2GHz, despite higher memory bandwidth etc..
That's how the G5 wins over G4, by clock!

All in all, if you have a new CPU core, you have to optimized the code for it.
An e600 core isn't the same as an e5500 or e6500 core.
The problem is, I don't see the developer (Morph or AOS) to squeeze the maximum out of this new CPUs.
You don't? Exactly what are you suggesting then?

Do you really think, FreeScale is that silly? To develop a new core (approx. ten years later) and the new one is slower than the old one?
They are squeezing out the last dollars of their IP by introducing SoC chips packed with new features they feel can be of value to their particular target markets (which is *NOT* desktop).
The PPC lives on legacy. For new developments in all markets previously covered by PPC, there are much better ARM offerings.
MorphOS is Amiga
done right! 
MorphOS NG will be AROS
done right!
