> That is a good point. If APM only meant to refer to the 460 then why the x?

I just gave it another thought and came to the conclusion that if we take the mentions of "40X", "44X" and "46X" not as relating to the CPU core but to the denominations of the chips it actually makes sense. After all, we know that Applied Micro have changed their naming scheme for new chips. PPC40x changed to APM80xxx, PPC46x changed to APM82xxx and APM86xxx/PacketPro/Mamba respectively, and PPC44x chips are not even listed any more on their regular website. So if we read the graphic this way then "TBA FY2010" (the leftmost one, that is) can actually refer to the PPC465 core based APM86xxx/PacketPro/Mamba chips.
