Lots of footage out there, sounds like. I was skimming through the NeoGAF thread and there is a ton of discussion and dissection of screenshots, but for my money I was most interested in the excellent .gif files they were putting up. I'll put a few up myself, but first I also found this excellent series of small bites of gameplay running at 4k on a PS4 Pro. Looks just incredible.
Stunning lighting effects:
