I've been talking about it for a while at the Linux/Open Printing Summits.

CUPS browsing does not play well with Wi-Fi networks (broadcast == run network in slowest possible mode), has usability issues on "unmanaged" networks without DNS or other infrastructure, and has management issues on "managed" networks (where network admins don't like to have regular broadcasts these days...)
Bonjour is the replacement, and we are working on getting Avahi support into the cups.org release so that all platforms can use it out-of-the-box.

I do yearly CUPS presentations that are archived on openprinting.org, and the roadmap page shows what is on the books at any given time...
