Honestly when you Include digital and bundled copies I'm guessing it's about a 50% decline and when you think bout how big halo was then to today it's not great but it's also not that unlikely
I don't know. Either way, its clear October massively disappointed. PS4 was very likely down YOY, XB1 barely kept its footing, and Halo 5 MAY have sold less than 1 million physical in the US. Like I said, we did hear Halo 5 sold roughly 1 million digital, so that MAY be a saving grace, but I don't know at this point.
