I haven't seen anything from Sony that would make me want to buy that system. But I have seen some things that would make me want an Xbox One.
Plus, I already realize like my Xbox 360, so it would be an upgraded and enhanced edition of that.
All things being equal – but the controller, I would still get a X1. I think the controller alone will be that much better (and I have used an X1 controller.) But I think there are more differences than that. I currently see Microsoft as a much more innovative company than Sony. I think they are pushing the future, and bringing it to us more than current Sony Corp.
Sony, was a great company, but seems to me to be just an empty bitter shell of what it was.
So, no, I am not going to buy a PS4.
