Well this generation of games consoles isn't about the hardware. It is all about locking players down into the "cloud" and other online consumer services.
Any hardware can be used for this quite frankly.
I wonder if the use of slightly less exotic hardware will encourage or discourage the homebrew scene. Afterall, I believe the reason why we still don't yet have a playable emulator for the first Xbox is because "it's boring".
I find it most interesting that both heavyweights decided to choose this type of hardware at the same time. It is almost like as soon as they realized it would not be "embarrassing" to do so, they jumped on board the x86 bandwagon immediately.
