Xbox one is the only console that allows me to play Halo,and quite simply has alot of money to secure 3rd party exclusivity content like dead rising 3 or Titanfall .
Basically if you love to play this industries biggest blockbuster games you can't go wrong with (Halo,Gears,Cod) and now (Titanfall,Dead Rising 3) even if the later turn up to be timed exclusives the fact that you are getting acess to content first is also very important and so far MS has proven to be very sucessfull with this tactic even sony has followed suite with their timed exclusives indies,wich brings me to PS. If you like to play indies the ps4 looks to be the right choice,and has for the 20 exclusives. I will ask the same question people asked at the xbox one reveal .
What makes you think that all of those aren't kinect games?(Just switch the kinect with move or indies).But since i know the power of sony's 1st party studios even if they closed some ( http://www.examiner.com/article/sony-restructuring-its-first-party-studios ) i will give them the benefit of the doubt.
But right now xbox one is the best console in terms of exclusives as far as i can see.
