I can’t speak freely about PS4, but now that some specs have been made public, I can say that Sony made wise engineering choices.

Thanks for the great event in NY @playstation - Very pleased with the commitment to 8gb of GDDR5 memory. Other specs are beautiful too!

8 GB unified mem as baseline for next tech iterations makes me very, very happy. Fun times coming ^_^

lots of memory is essential for both the CPU & GPU to create large & alive game worlds

If Killzone was running with 4gb gddr5. Well ****. Great move by Sony providing they can shift the hardware come release. Developers seem very, very happy with this.
Epic co founder seemed very happy on Game Trailer's after show
