what I see is sony being interested 100% for their pockets, everything else -especially the 'for the gamers' motos- being basically ads, means to increase profit.
the amount of sony funded games consistently pushed back, the relative lack of big $$ projects, and basically their replacement with the wealth of "cheap" for publishers indie games (and "elevation" of those to AAAkind though ..yes, marketing) etc, even their policies on psn and digital $$, they're all facts that point to one direction, if you care to align them.
so I believe that whatever PD does, it will have to do primaily with it beign an asset for further "ads", than substantiallity.
and siting here, three years in, with nothing but thin air from pd, its a reality that kind of reinforces my thoughts above.
