AMCC?  I have no idea.  Maybe not.  Freescale certainly seems to be.

That they are.

New ones.

They are not intended as replacements, just alternatives.  Some people
have powerpc code and see no reason to port to a little endian platform
(which can be a pain in the rear).  Some would rather have more options
for CPUs and would like ARM.  The IO bits seem to be identical between the
powerpc and arm chips, so at least that only needs to be developed once.

Now I suppose if demand disappears they will change their plans, but at
least the place I was working until a few months ago, we were told that
they were going to continue designing new powerpc and arm chips.
We explicitly asked if powerpc was a dead end going forward (we were
already using freescale ppc chips in some designs, and arm chips in
other designs, so either was an option for us).

I do agree that people are not running little endian on the freescale
