I will simply say that at first, I was fully ready to embrace both PS4 and Xbox One in this generation (as I have both PS2 and PS3 and Original Xbox and Xbox 360). I always felt that by owning both major consoles of a given generation, I got around the exclusivity problem.
But this generation, Microsoft really shot themselves in the foot, and continue to do so. That turned me off from even looking at an Xbox One....as I have no doubts that sometime in the future, they will try to reinstate the policies that turned a majority of gamers (many of whom were at one point the Xbox Faithful) against them in the first place. So, this means I'll be missing out on the future of the Halo series...but so be it. I have Destiny on PS4, and am loving it. (I was glad to see Bungie get out from under the Microsoft thumb).
For those who have Xbox One's, I am happy for you, and I hope the console brings you many years of entertainment....and I will hope I am wrong about the (widely held) notion of MS reverting back to its initially intended policies for that console. But any love I had for the Xbox brand died with Xbox One. 360 is as far as I will go.
