CBS 2 News seems to be testing out something on wcbstv.com. On top of the link for the live stream of CBS 2 News at 11:00, there's a graphic telling visitors to watch the noon newscast. What's noticeable is that the logo appears to be different. Instead of "HDTV" beneath the eye and the 2, it's just "HD" to the right of it.
Interestingly, the May 2010 "sweeps" period begins in just minutes.
