Sony still not pursuing backwards compatible for PS4.

[darkenergy]

Despite news of backward compatibility on Xbox One, Sony still doesn't plan on implementing similar technology on PlayStation 4.

"The announcement didn't change," Sony Computer Entertainment head Shuhei Yoshida told Polygon. "I don't think we will change our approach. The PlayStation 4 doesn't have backward compatibility."

"Backward compatibility is hard," he said. "I won't say we'll never do it, but it's not an easy thing to do. If it was easy we would have done that."
