When the Boot Camp support Windows 8 drivers?

You should visit the Bootcamp forum where your question has been asked and answered 100s of times. https://discussions.apple.com/community/windows_software/boot_camp.

There are no Windows 8 drivers for Windows in Bootcamp. We are users and have no insight regarding when Apple will release anything. Windows 8 will not work correctly in a Bootcamp partition so install Windows 7.

Back when Windows 7 was initially released, it took 89 days following that initial release by Microsoft for Apple to release supporting drivers via Boot Camp. If past is prologue, we are looking at roughly January 22nd or 23rd as a possibility. That said, no one knows for sure except for Apple. Also, as BobTheFisherman pointed out, the Apple Support Communities consists of user-to-user support forums. That means no official word will come from Apple in these forums pertaining to the release of Apple software. Moreover, Apple generally does not announce specific release dates for any software or hardware, but rather will occasionally announce a target month when a high priority piece of hardware or software is to be released. Most of the time, Apple does not give even a hint of a release date for lower priority releases, and Boot Camp is likely a lower priority release from Apple's perspective.

apple nose must to be broken,

apple sell out that good hardware, and they still want to control how we use it,,, what a ****!!!

Go ahead, it's your choice.

There is no "likely" about it. Boot Camp has always been a low priority for Apple. I would venture to say that once a set of Windows 8 drivers is released, they will never be updated unless MS makes a major change to the OS that renders something unusable. Once you get that initial set of software installed, it will be on you to find updates for important hardware (eg graphics card), just as you have in the past.
