here ya go OP. This was rendered in real time witht he PS4's hardware. Just to give you an idea of what its capable of.
Heres a table that should answer any of your other questions, of "how and "why" the Ps4 games will look better.
You are already familiar with how good some of the PS3 games look. Compare the specs, and expect greatness.(I edited in the $399, because it was a little outdated *pre-E3*)
