Short and simple, no BC. Although I don't give a shit to BC since I definitely wont be playing 7th gen games on a 8th gen console. But still, now that most devs can use cell processor effectively and a 22nm cell processor would be awesome, it just feel bad how all the knowledge about cell would be wasted.Rumors are probably true that AMD processors are in ps4, but I don't see an APU config as powerful as discrete ones.
Not to mention most sony first party devs have their own proprietary engines customized for cell, like ND etc. I doubt those devs would want to have a learning curve again.
So whats your take, cell or no cell?
