I might buy an Xbox One but probably not for another year or so. Other than Peggle 2 and Forza 5 there isn't anything on the console right now I'd want to play and I'm not sure Sunset Overdrive, Project: Spark and Quantum Break are games that would make me run out to buy the console.
I'm plenty happy with my launch PS4 and I probably will buy the Wii U before I buy the Xbox One. Kudos to Microsoft for finally realizing nobody wanted the intrusive camera. I still question the horsepower under its hood. I expect that only XO exclusives will be played on it if I ever buy one and it will be some time for a good number of them to be on the market.
