Just a brief review from Adam Sessler on the DS4. Pretty straight forward, he was pleasantly surprised. Nothing earth shattering. However, it greatly alleviates any worries I had walking it. The DS3 was terrible for shooters. For a more in-depth (though borderline fanboy) look: I also found this recent vid where the youtuber breaks down all the different aspects. WARNING: The guy is a little excitable. http://youtu.be/G7tQqEEww6g
I don't watch that guy. I've been following him since the Xbox 720 rumors and found some of his views to be stupid.
