That is impressive if each of those worlds is loaded as you go, but I feel like both Microsoft and Sony were holding off on this next generation until graphics tech got better. We still are nowhere near photo realistic, cinema type game play (and yes I realize that such animation has to be scaled down a bit because it can disturb people if it's too real, but we're not even at that point yet). Real time ray tracing was going to be nVidias whole push into a new generation of 3D graphics, but that turned out to be not all that impressive (and with huge performance costs).
