Doesnt really matter what they do at this point. Unless they're including a blow job with every console it will not outsell Playstation. The playstation brand is just too powerful around the planet for Microsoft to really be able to compete with them at the same time.
The year head start of this gen made all the difference because a lot of parents are not going to buy their child 2 systems. Most adults are not going to buy 2 systems. Most people will stick with whatever they buy first. Especially casuals. Microsoft cannot compete with Sony at the same time so regardless of what they do the xbox one will be the loser this gen.
