Halo has always launched in September or November, two months with sales traditionally higher than October. Also, October is one month before the biggest sales deluge in America. You think people are gonna pay 350 for a console when they can get one for 299 with a bunch of free games? Hell, Xbone was up 81% YoY. Look at it this way: last October Xbone sold 168k, then went on to sell 1.2 million the next month. PS4 sales are essentially flat YoY. Again, this is right before Blck Friday month. Were you expecting 400k+ sales over a 50 dollar price cut right before the November sales rush. Please. Insane deals and massive holiday sales are the new normal. The sky isn't falling.
This is always how it goes. Consoles are dead until they aren't, blah blah blah.
