I like the Epic answer and like I supposed before the PS4 demo is a lot different from the PC one... PS4 demo is merge between the old PS4 demo and the extended PC demo with different details (even a mountain).
About the SVOGI it won't be used even in PC in the next five years... PC needs at least a new GPU hardware generation to begin to work in games (not demos) with SVOGI... same for PS4... both are weak to do that... the same case with Ray-tracing.
And I expect the tessellation to be fixed for E3.
Everything else is the same in the demos... AA, meshes, textures, etc.
