How Will Nintendo Achieve BC next generation, if they do?

The DS has an identical GBA ARM7 chip that acted as a sound processor when running DS games. Plus the DS's main processors were ARM9.

Ok, thanks!

So, I guess short of them using PPC architechture again, they wont really be able to physicly provide BC then?

If they put a less energy-hungry version of the Wii U's CPU on the motherboard as a secondary processor (responsible for sound or background processes), but that would certainly increase manufacturing costs and hardware R&D. Also I'm not familiar with how micro-architectures work and whether or not this would make programming harder. I would think there would be an inefficiency because the code would have to be interpreted between processes, but if it is a secondary processor maybe it isn't a huge concern other than limiting bandwidth.
