Not intending to crap on the good intentions of including PunkBuster in the patch, just be aware that PunkBuster seems to sometimes adversly affect the implementation of non-cheat based mods (defined how broadly by PunkBuster, I am not sure but FarCry players were getting kicked for modified pak files and skins), as well as cheats. Also, if there is a patch subsiquent to the implementation of PunkBuster, i.e. T:V 1.2, patching the game seems to induce more of these Whitelist kicks.
But still better than a Panzer Autoaim world, just be ready for it.
Check out what happend to the FarCry multiplayer community regarding PunkBuster after the 1.3 patch was released recently, and if you have a Geforce 6800 card, get the 1.3 patch and play FarCry single player. The new HDR lighting effects will make you forget about anything multiplayer until the December T:V patch.
