It is officially announced (sort of, as good as it gets). The next gen high end Nokia smartphone will have a ST Ericsson U8500 ARM Cortex-A9 (dual 1.2 GHz) and a Mali 400MP GPU.

IMO the N9 will have this spec, but it is not clear if it runs MeeGo or Symbian. There could be several devices though, but it looks like the MeeGo/Harmattan (the original N9) is scrapped altogether, both the original HW and the OS.
