Being too cowardly to take P5 out of its box yet (cowardice not the only reason, really), I would note that even while there isn't a light year's difference between the renders (sorry 'bout that pun), we users have had years to work on creating good lighting for P4, and Kiera and Blackhearted are two of the most talented P4 lighters of which I am aware. That Kiera is producing ff renders of the quality above in such a short time after P5's release is good news, not bad news, IMHO.
