Its all a sham.
This gen has so far been dictated by media propaganda and agenda campaigns. These systems are to close in performance to have such a natural disparity.
Look at articles like the that have been around since before the consoles were even released claiming victory for Ps4 not even 2 years in to the cycle.... before these systems even started getting software that was actually created for them.
But I say the X1 still has a couple aces up there sleeve. Look at the fear in the media. If they felt the Ps4 has really won they would call off their dogs. They have a 2:1 lead in sales yet we still get kinect slander articles and constant resolution comparisons because they darn sure aint game comparisons since they dont focus on the 98% of the game that is identical. Features the X1 had since launch go ignored until Sony has them. If the war is really over sony can call off the troops.... but they wont. We have at least 100 million consumers to fight for. Thinking that an over lapping 30 mil (because some people own both) is enough to call the gen I would call you stupid. Yes Sony has a commanding lead but again these consoles havent even hit their stride. The core gamers are almost dried up. At this stage a 10 million lead can get erased with 2-3 blockbuster exclusives.
But in truth MS real problem is the media.... they need to protect and clean the gunk off of their consoles image. Their fight is really with the media not Sony.
But again this is all a sham. You dont need to sell the most to be successful or even provide the best experience. MS has strong enough position in gaming were they wont lose content and can still make money off of what they release and that all you really need.
