To justify such high specs the game better look and play the part. I really hope it does, as PC gaming has always been about pushing the edge. There really isn't any excuse for gamers having less than 8GB RAM and the eight-core CPU recommendation lists an Intel 3770K (a 4-core CPU with hyperthreading) so that looks mostly aimed at AMD users.
As for console versus PC, the XB1 and PS4 are limited to 30fps and run sub-1080p/1080p - as long as the PC version isn't framerate limited then it's a no brainer.
