Recently since E3 there has been a lot of back and forth over who is more deserving of our gamer dollar, Microsoft or Sony. A lot of the rational being used in support of one or the other has to do with features that not only don't currently exist, but were only described in marketing speak. There are places in both keynotes that the companies in question gloss over unseen tech with grandiose statements. Cloud gaming was a major standout on this front for the Xbox One, Gaikai was the same for the PS4.
