I actually haven't seen anyone post this one yet. It's one of the few that I have seen that seems legit, leaked from Indie Gamer Chick. She is connected with several Indie developers and has her finger on the pulse pretty closely. Apparently NX is "technically" more powerful than PS4. How? No one knows, it seems as though Nintendo might have something up their sleeves though : )
