I say before the year ends the 360 will overtake it. All the games coming out at the rest of the year will only appeal to existing x1 owners and multyplats will only boost ps4, so I see nothing that will give them a big enough boost.
The only thing I see that can give them a boost is bundleling, but they got only sunset overdrive wich might appeal to consumers, outside the xbox fanbase and I dont think that will be a lot.
Prediction: It willl do much worst then the 360 second holliday, no more than 7m ltd by the end of the year.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
