Received word today that Canon has 2 lenses planned for announcement on January 3, 2012. That’s a week before CES.
The 35 f/1.4L II and the 24-70 f/2.8L II are both mentioned. The source claims there is no IS in the 24-70.
The source has been right about lenses in the past, but I’ll keep it at [CR2] until I hear from others.
