My apologies if this has been pointed out, but here's something else that might point to the camera not being bundled.
Here's the original PS4 page after the Feb. conference:
http://web.archive.org/web/20130516032443/https://us.playstation.com/ps4/
It talks about the "new ways to play" including the Dualshock and new PSEye.
Now here's the new current page:
http://us.playstation.com/ps4/
Some pictures of the camera, but
zero mention of the PSEye anywhere on that page at all.
Seems a bit strange to do that if it were bundled with every system. Huh.
