I don't think we will get the denver cpu cores. They weren't in the development kit specs and are probably more expensive to license needing payments to both nvidia and arm and arm licensing is much cheaper. Those arm cores are already massively more powerful than wii u and quite competitive in performance terms. Something like 30-40,000 mips. So I think there is a strong chance we won't get the denver cores.
Also Nintendo needs to make room in the SOC for some frame buffer memory if its using shared memory with no dedicated video memory. They need to adapt the SOC to work with lower cost external components like DDR3 memory and they might adapt the SOC to make compatibility/emulation of 3DS and DS easier for digitally downloaded games as well as improvements to make the hacking of their console harder and more secure.
