BC is a problem only if they get it sticking to very old generation PowerPC CPUs, POWER architecture is very scalable, and with an APU made of a scaled-down POWER 8 CPU plus a GPU comparable to the competition they could both get BC and easily outperform the mid-range x86 solutions (they are mid-high end considering APUs only, but mid or mid-low-end compared to the whole offer of x86 CPUs and AMD or NVIdia GPUs) used by MS and Sony. Porting to POWER based architecture isn't a big problem, first because since the last gen consoles too started using a higher degree of hardware abstraction, getting their performance advantage compared to a PC of the same power thanks to HAL, drivers, libraries and OS optimizations for a single HW configuration and not letting devs anymore using low-level tricks in the application layer, second because neither data and address alignment is a problem, as it was instead in very old times porting between x86 and 680x0, as POWER can use both little and big endian.
