I found an older document from mid-2011:
http://www.socip.org/socip/speech/pdf/20110708-075811-CCORE-SoCIP%202011%20Presentation.pdf (translation)

From page 7 can be seen that the C8000 has the PPC460 core while the C9000 has the PPC470 core (or more specifically PPC476 according to page 18).

Some C*Core press releases from yesterday mentioning C8000 and/or C9000:
