I have zero concerns about what Sony are or are not doing right now WRT next gen. There's really nothing for them to gain by making their moves public before they are in a position to profit from the release of that information and there's really no reason to believe their silence either through official or unofficial channels is indicative of a lack of moves or an inadequate or incomplete plan for next generation.
Historically, Sony have been very good at making money selling video games and my default expectation (minus solid evidence to the contrary) is that they will continue to do so.
Normally I would agree but the reality remains that all three companies kind of laid a dud the generation after they released their best hardware to date.
N64 after SNES, Xb1 after 360 and PS3 after PS2 fiascos for myself don’t create the upmost confidence in the ability of these companies to not shoot themselves in the foot.
