First week 2016 will probably suffer a bit since what the other years had as first week became the 53rd week of 2015 instead. It may still be enough to beat the first week of 2015, but will start trailing behind the other years for sure. With Pokken, TPHD and Starfox coming in March and April it should surpass the previous years (2014 and 2015, not so sure about 2013 which will get a big head start) until their respective releases of MK8 and Splatoon at least.
