Nobody is saying that, do you think MS would have been doing all of their promotions and incentives to get a XB1 if they were not getting whooped by Sony on their home turf?
No, and they need to, because, as you said, they're getting whooped. Sony is not getting whooped, they don't need to do anything.
Competition is not good, it's neutral. The Xbox getting whooped becomes good for consumers because of price drops but bad because of situations like Tomb Raider being bought to, more than likely, compete with Uncharted. Good and bad. It is not inherently good.
I simply don't understand why people believe a month loss of less than 20k will give Sony a kick in the pants or why it's "deserved" by MS.
