I don't know how to put this any other way. This is factually incorrect. Obviously, the APU might be the biggest bottleneck in terms of optimal performance, because that's essentially doing all of the processing, and the RAM supports it. However, if a technical limitation comes up that is impeding the performance of a particular aspect of a game, it's almost always because of its memory footprint. I have literally heard conversations where modifications had to be done to the audio engine because its memory footprint had to be cut in half due to a push from management to free up RAM to try and achieve 60 fps on our game. In fact, last generation, Sony released an update that reduced the memory footprint of the OS, and gave developers access to an additional 70 mb of RAM. Why would they put in the effort to reduce the memory footprint of their OS by 30-40% if developers weren't maximizing the use of the available RAM on their console?

RAM is absolutely critical, and having less of it is definitely a game development limitation. You won't come across too many PS4/X1 games that aren't using every single megabyte of RAM that is available to them.

I clearly remember reveal of PS4/XB1 when developers were very pleased with amount of RAM with PS4/XB1 and they actually were saying they can be very relaxed with development with that amount for RAM. But some developer were saying that CPU is actually huge bottleneck, because amount of RAM is huge and GPU is powerful but CPU is weak. 8GB RAM in PS4/XB1 is definatly not bottleneck, actualy you are first person that I heard saying something like that.
I really dont see point of comparing PS3 512MB RAM with 8GB PS4 RAM, of course that in 2010. 256MB of RAM for games was little for those games.

Okay, so you ackowledge that the 256 MB of ram the PS3 had at release was adequate, but in 2010, four years later, the extra 70MB released to developers was a good move, because memory was starting to become an issue. However, with the PS4, you believe the 8GB of RAM the console had at release was adequate, but there's no reason to think this is starting to limit what they can do on a console? Why do you think this?
Furthermore, Mark Cerny appears to disagree with you. If RAM was a non issue on the PS4, why did they add an additional 1 GB of slow RAM to free up more of the GDDR RAM for development purposes?
