The price point is going to let Sony crush Microsoft, but someone I follow on YouTube went to E3 and talked to an 18-year employee at Microsoft who eluded to the fact that the Xbox bundles might help tip the scales.
Consider if the Xbox One ships with 3 free mediocre games - that instantly makes it the cheaper console. They don't even have to be good games, but just that they're shipped with it will pull people back to the Xbox. And we've seen them do this with the xbox 360 launch.
Not to mention there is a reputable rumor from Wired.com that every multiplayer game will have access to dedicated servers on the Xbox One because of their 300,000 cloud servers. If true, that is a MAJOR plus factor for the Xbox One.
