Nah, i think most people that want GOW already have a PS4, modest boost to hw, i think less than 100k boost ww.
I think that's about right. This is an established Sony franchise. Most fans of the series already own a PS4. The strong reviews will certainly more more than zero PS4s. A noticeable number, maybe. Huge, no.
I'm new to the series. I was on the fence, but the universally high review scores have basically guaranteed that I'll pick the game up this week. I already own a PS4 though. If I didn't, I don't think I would buy one just for this game.
