All I know Microsoft has to act fast. The more Playstation 4 is selling, the more developers are going to use it as main platform and port the Xbox one version.
Microsoft doesn't have a huge first party studio's collection, They mostly make deals with 3th party, now it's getting way expensive, because they have to compensize the sales the developers misses (if we talk about exlusive deals).
Right now, Xbox one has a better game library. They should take adventage of it (somehow). In the future we get project Morpheus and Playstation Now. Sadly, we don't have a lot of information about it, but it looks promising. Especially Morpheus looks interesting.
What does the Xbox One has for the future? Sorry, I'm not that well informed, perhaps I missed something.
All what I'm trying to say, Microsoft show us what you got for us at the E3! Sony, has extremely much luck with all hype, strong brand name, better hardware and is known for a long support.
Once you entered you won't be the same anymore. A blog about life.
