Apologies to Dr. Peter Venkman, but it's hard to believe that it's taken this long for a webcam vendor to encroach on the vacuum left by the discontinued iSight, even though we have hints that a new model of the Apple camera might be on the HD horizon. Logitech has now announced the QuickCam Vision Pro for Mac, featuring "premium autofocus technology and Carl Zeiss® optics." No word on whether the camera will feature fine Corinthian leather or Posi-traction, but there's hope.
Seriously, though, the camera does offer a voice coil motor for autofocus, RightLight exposure technology and a 2 megapixel sensor; this should allow for VGA-quality (640x480) videoconferencing and 720p HD (960x720) local video recording. Snazzy! Logitech expects to ship the unit in July for an SRP of $130.
Update: Commenters point out that the product is quite similar to the QuickCam Pro 9000, which isn't billed as Mac-compatible but actually works just fine with Mac OS X 10.4 and 10.5; it's also list-priced $30 cheaper. Hrm.
