Xbox One had a very bad 2014 until holidays.... you will notice much better April, May, June, July and August in 2015.
With Halo 5, Forza 6 and Rise of the Tomb raider coming out this holiday ..... Xbox one will outsell last year numbers. 2015 is probably going to be the peak year for Microsoft.
Look at the following thread even the PS4 is doing better. With the release of Witcher 3 and Batman big AAA titles these numbers should be improving compare to last year.
