Can MS & Sony just simply make next gen fully BC?

I think you're comparing the PC emulators, which isn't a fair comparison because that isn't equal optimization. I'm simply pointing out you still need a powerful CPU to make PS3 emulator run well on a PC. Hence, I'm reluctant to believe PS4's CPU can emulate the PS3 well.

Not sure you are understanding anything... So I will try another method.

Why do you think the PS4 is unable to emulate the PS3 well?

Xbox 360 BC started rough, improved significantly, but still has limitations likely due to the hardware. Not every game is a locked 30 or 60 fps. Halo: Reach was a fairly early BC release and the biggest issue was frame pacing. It really feels like BC performance has hit a wall and I don't believe Crysis is gonna see much improvement in performance.

If they decreased accuracy they can increase performance.
A SNES Emulator with 100% accuracy can bring down even the fastest CPU's today.

I think you need to take look at how Microsoft is actually achieving backwards compatibility though. - It's not pure emulation.
