I couldn't care less for MS or Sony, so i'm not a supporter for one or the other. I did buy both xbox/xbox 360 and enjoyed them.
As it is now, I won't be buying an Xbox one and it's not a game issue(Off course there will games, MS is not retarded). I'm currently living in Dubai, and quite frankly even if MS had some sort off deal with retailers for used games, I doubt it will apply for most of the middle east. Same for live Tv. I buy lots of games and for each 10 I buy, I'd say 3 are used(mostly TPS/FPS, play them for single player campaign only) so it does matter to me. Also, I'm against DRM in all forms and thats why i don't even use Steam(still buy physical). Not even going to mention ads on dashboards or my dislike for motion control, so yeah no xbox for me.
