Not a tough call for me. I don't care for the slew of restrictions on Xbox One which PS4 will have NONE of. Easy decision for me. I refuse to support anti-consumer practices and alienating a hardcore fanbase.
Destiny is on PS4, compliments of Bungie. What could you possibly want thats exclusive to Xbox? Tired ass Halo? A racing game? don't get me wrong. I'm currently an Xbox and Xbox 360 advocate, but PS3 was recently added on and so will PS4 in the coming months.
Killer Instinct, Halo, Gears, Titanfall looks good, I'm used to play COD & stuff there. Yeah Sony hurt Microsoft with E3 but I value games rather than price tags or any other factor for that manner. Which is why I fail to see all the madness. I will get both anyways. 1 this fall, 1 in January.
