Let's settle this.
PS4:
-Has already sold 2.4 Million in roughly 4 weeks. It hasn't sold more due to stock limitation.
-Has 2 retail exclusives yet it's selling at a very high rate, showing there is tons of hype surronding it.
-Great lineup that will push consoles in 2014, even more so then they are being pushed now.
-Strong 3rd party sales.
-Strong 1st party sales.
Xbox One:
-Has already sold 1.9 Million in roughly 3 weeks. Hasn't sold more due to lots of faulty units, but the kinks in the hardware will be ironed out soon.
-Has 4 retail exclusives (If KI doesn't have a retail version than 3 but I'm pretty sure it's 4) One that is big, two that are niche, and one that is bad. Yet it's selling at a high rate.
-Great lineup that will push consoles in 2014, even more so then they are being pushed now.
-Strong 3rd Party Sales
-Strong 1st Party Sales
It's too early to predict doom, and I doubt the sales momentum will come to a halt for either of the consoles, so every arguement saying that either console is doomed is invalid.
