People are getting a little overexcited about the Cerny interview.
I think the whole raytracing thing is being overblown here. There is no way you can get full ray tracing hardware into a $400-$500 console. My guess is when Cerny talked about ray tracing and sound processing basically in the same sentence, he was thinking of some ray-casting solution for sound. Done by maybe something like the Tensilica chip inside the XBox, sort of a Tensilica+. "Sound casting" is it if we want to invent a new name. This would essentially give "Sensurround" to consoles.
As for the magic ssd, I don't think there will be a terabyte(s) ssd (again, price matters), I'm thinking there will be a really fast ssd buffer in the 128G range, enough to "turbo-"stream enough graphics, and so there won't be any need for more than 16-20GByte of ram.
Again, the SoC alone will probably be in the $150-$200 range, there is a limit to what you can build with the rest, given monetary constraints.

Not saying you are wrong but I have a hard time believing that Cerny of all ppl made a mistake here, especially in what is most likely a pretty controller interview.

That said, Digital Foundry have claimed that the hardware details Sony have announced actually does support ray tracing, and that Nvidia have been able to give older graphic cards through software. So Sony's solution could be software based though an employee at Naughty Dog seemed to suggest that it is actually hardware based.

More possible is a chip or part of the GPU have raytracing capabilities on a very simplified way. Perhaps just a way to use prebaked solutions made based on raytracing less taxing to the system.
