Yes, they seem to phase out PPC with the PPC465 core. I had thought they would make the jump to the PPC476FP core, but didn't happen.

You mean the high-performance embedded PPC market? If so, there's still LSI with its Axxia line of SoCs. It was PPC-only (PPC476FP) originally but got ARM members (Cortex-A15) recently. So they're in a similar situation as Applied Micro, i.e. offering existing PPC chips for some years to come, but eventually switching completely to ARM and ditching PPC.
