Not really. Most people already have a PS3 if they want that feature, a feature that would make the Ps4 fucking expensive.
Someone to correct me but pretty sure the PS4 hardware is completely different to PS3. You would basically need to build a PS3 inside the PS4 for it to work. Which makes no sense when PS3's are becoming dirt cheap.
You're an idiot. Of course it sucks that games aren't backwards compatible, if that feature was easily implemented it would've been, but it sucks that it wasn't.
