Yeah saw that earlier but also noticed what Dave did that the "pressure" part was very speculative with no quotes. Probably more interesting is the quotes in the article from Andrew House ...
""Certainly for the earlier part of the lifecycle, the vast majority of the audience that we speak to tells us that their primary wish is for the full controller interface and there's not necessarily a huge emphasis being placed on camera interaction," House says.
In some countries Sony will offer a launch-day bundle which includes the camera, a decision to be made at the regional level closer to the launch date. House is prepared to "adjust messaging" over the time – indicating that Sony may bundle the camera with every PlayStation 4 further down the track when it is ready to target a wider audience."
It gives some good reasoning and an indication that it may be bundled later in the consoles life as pricing allows.
