I think the extension of mobiles - dongles and Smart TVs - are what rule the living room, running services born on PC and mobiles and not consoles. That is, if someone wants to add streaming video to their setup, they'll buy a dedicated device, even if just a £35 Fire TV dongle. The access point to the content, the thing everyone wanting to 'control the living room' was after, isn't consoles and won't be. Consoles have just become a device for these other services, making the prospect of monetising the whole family's content unreachable for consoles. People will be buying Amazon and Google and iTunes movies and music, not MS or PS movies and music. And that's why these content services are being extended to mobiles.
