Well, I will assume if you want to believe that, you are entitled. Largely, most know that marketing and PR was the focus of the event, and what better way to appeal to a core gamer than tell them there is core games and core focus.
Their attitude is clear, they are starting to focus more on casual (assuming the eyetoy is included). Motion controller is default. Tablet/phone like touch screen on controller is default. Move lights in controller is default. Motion camera is default. More casual games is their focus. Luckily they won't leave us core gamers behind, but Sony has clearly changed focus looking at the success of the original Wii, tablets/phone mini-games, Kinect as well as Move, and all the consumers it has brought in to gaming. PS4 is one more step to CasualStation. I hope they don't forget about us core gamers though.
