Ok cool at least you provided a link. Despite having a bias I cannot go against truth or facts. It is what it is. What pisses me off more than anything is when people blatantly lie (and they know they're lying) despite having or seeing the truth right in front of their face.
Now I will say that you provided a link but as you can see there are posters understandably questioning just how authentic that tweet is since he did use the words "ps4 dev environment".
I guess the ultimate truth will be revealed when both versions are released next month.
