I was thinking ever since xbone got 360 backwards compatiblity people have asked when will PS4 get it. I believe the reason why it hasn't happened was because PS4 was unable to emulate the PS3, but with the more powerful NEO coming they have finally figured it out and it will be a NEO-exclusive feature much like SNES-games are exclusive to the New 3DS

First of all. Xbox one doesn't have backward compatibility. Microsoft is basically porting the xbox360 to Xone for free. That is why you need to download the games even though you have a disk and that is why not all games from 360 are playable. Could sony do that? yes but they already have a service like PSNOW so chances are they won't.

Could they make a proper backward compatibility? impossible! Not only PS4 has a completely different archtecture(x86 vs Power PC's Cell from PS3) but a software emulator would require a really strong CPU(specially because PS3 was a very CPU focused machine) and we all know PS4 has a shitty amd CPU.

Actually.
Microsoft isn't "Porting" the Xbox 360 games to the Xbox One.

What Microsoft has done is virtualised the Xbox 360 software environment, they have then "Emulated" the specific hardware components which is then abstracted/translated to the Xbox One's low-level API's.
Then Microsoft has repackaged the games, which is why you need to download them.

Basically it's a little bit of Emulation, little bit of repackaging.

Keep in mind that GPU's these days are compute monsters, they can pick up the CPU slack... And that Jaguar is superior to the PS3's Cell. (Seriously, look at the amount of games with higher player counts and on-screen characters relative to last gen.)

The PS4 and PS3 are just as different as the Xbox 360 and Xbox One from a hardware perspective.. It's not an excuse.

The Cell has also proven it has not been a hindrance to Emulation as PS3 emulation on the PC is farther along than the Xbox 360 emulation.
