The main reason XBONE is selling slow is resurgence of the PLAYSTATION brand.In PS2 days PLAYSTATION dominated everything,it was a common name in pop culture,you cud see it everywhere,SONY was one of the top BRAND names in the world close with MCROSOFT,COKE,EXXON MOBILE,GOOGLE,YAHOO,etc
then came the PS3 and PLAYSTATION bombed and SONY also took a big hot and the losses were massive,it is estimated SONY lost $7.5 Billion on PS3.
but even after PS3 bombing,PLAYSTATION kept up because of PS2,PS1,PSP GOODWILL to its brand name and the fact that XBOX has no brand power outside USA and NINTENDO didn't have brand power outside JAPAN and USA so PLAYSTATION was still big worlside and also big in USA & JAPAN.
even after PS3 bombing,it defeated X360 and came close to the Wii.And everybody knows and even knew before that Wii was a one hit wonder and it also won as PS3 bombed which contributed to Wii success and the sole reason X360 suceeded was PS3 bombing.
When the new gen started,Nintendo flopped and XBOX went back close to XBOX 1(original) success and PS4 and SONY went back to top
XBONE launch has a little to do with it but anybody following gaming industry for the last 10-20 years cud easily tell you before how this gen was gonna pan out
