I expect PS4 to pull away even further, as the problem with Sony, is meeting demand, a different problem from MS, which have supplies stacking up in stores already. Less than 2 month after launch, XBOX one is already Not selling every unit they made. The real work only now begins for them, as most of the hardcore gamer have already bought theirs.
Sony is still in Honeymoon, but I expect similar situation in a few months time, especially if there is still no compelling games.
Imagine if they launched in more nations, some of these xbox on the shelves would have been bought by people. When they finally arrived, they may have already lost sales to Sony.
MS need a price drop, or the big boys like Halo & titanfall prove to be system seller to be on touching distance with Sony's numbers.
Or better, a price drop with Titanfall/halo burden in. I do not foresee any big game from Sony in 2014 that can match MS, which is a positive news for MS.
However, it seems Sony doesn't need exclusive, when 3rd party games looks better.
