I hope not.
Yes, early adopters and hard core gamers are programmed to think that BC is a major selling point, but what it really means is either:
A) new generation hardware architecture is an evolution of the prior generation, thus allowing for straightforward compatibility (like upgrading a PC with a new CPU, a new GPU and more memory).
B) new generation hardware includes prior generation chipset on logic board, increasing cost and complexity. Cost that could have gone towards increasing memory, more compute units on the GPU, more cache on CPU, etc.
Nintendo would be better off going with the most cost effective solution utilizing the most current chipsets and memory while yielding the most computational power for that cost.
I don't see any benefit in keeping the same PPC architecture; there's no serious development or push towards its improvement. It's actually one of the reasons why Apple went from G5 PPC to Intel years ago.
