Not a given since emulation incurs large performance losses. But since the core counts line up... maybe. And if so, if it would ever be implemented. Backwards compatibility would make it a day one purchase for me.
The AMD processor they're using wouldn't be anywhere near powerful enough, some guy was hacking on a very basic emulator and said it would be a 50:1 CPU power factor and that we might not see a proper emulator for a decade. They will be using some form of Cell SoC to facilitate the streaming of PS3 games I imagine. The PS4 will just be running a streaming client for those basically.
I am disappointed in lack of BC but if it can help make the price more palatable and they have good launch games then I don't think it'll be a hard sell.
