I think what is almost as interesting as the NDC bundle movement is the fact that the Gears bundle hasn't managed to overtake the regular Star Wars bundle yet.
Also interesting to look at last year's rankings.
Xbox One sold 1.2m, and on Amazon it had #2, #82 & #100.
PS4 sold 820k and placed #11, #31, #48 & #79.
PS4 currently has #5, #15, #22, #24 & 31. Pretty good preorders as well. Also has possibly one more update that would count in November's NPD.
Massive difference between the top few places and what comes after it would seem.
