Probably an accurate prediction. The days of CoD dominance are over in November. PS4 has a bigger install base in the US and even if X1 sells more copies, it won't be the 2 million difference of past years. There's a 50k difference in NA with Ghosts and PS4 will trounce it world wide regardless.
The gap will continue to grow every month. The sports fan is already on board with PS4 with the Madden news tonight. The shooter crowd will likely take time to move over but Destiny will help move that along. The MCC is a great value and service to fans but it won't change the game. The last castle that is CoD will fall in time.
