Thanks to the people who let us know that the Punkbuster site has been updated with the news that the guys behind the software (Even Balance), announced they are working on Return to Castle Wolfenstein support. And this time they got actual developer support as they were actually contracted by id to integrate their anti-cheat tech. Here's a bit from their announcement.

We are working hard to get the integration code written and tested for an upcoming patch to the game. Based on preliminary work, we fully expect to be able to support and enhance all areas of the PunkBuster system and sustain only a brief beta period with RTCW. The PunkBuster software will still be a separate and optional addition but will be directly integrated with the game when it is enabled by players and server administrators. As always, there will be no direct cost to players and server admins for non-commercial use of PunkBuster and we fully intend to support the clan and league communities, as well as mods that develop around RTCW with both free and premium support services and add-on software.

It will be interesting to see what these guys can come up with now that they have actual support from id, as Punkbuster for Half-Life never really worked the way it should.
