Along it being shipped (according to Gaf), and how quick this game was discounted with B1G1F and 50% off deals, I can see why MS might be disappointed with Halo 5 sales. They were probably hoping the first 3-5 million still throughs would be mostly at full price not discounted.
This is the only way both statements (5million shipped and MS being disappointed with sales) makes sense to me.
