I do not know if i am just lucky but everything is working correctly and without problems! (only not-working is the keyboard light but i really do not care about it).
I have no yellow/unrecognized-devices in my Device Manager, "sleep" and "wake" works as it should, WiFi works and generally, i now have a fully functional Windows 8 on my mbp. Also, the two most common non-working devices (as i see here in the threads), the trackpad and the superdrive are working correctly too. I tested my external stuff (monitor, keyboard and mouse) and have no problems too.
My system is working this way for 3 days now. I will post here if something happens.
One question though:
Some day, Apple will release their official BootCamp drivers. Will BottCamp-control panel allow me to upgrade the drivers or there is another way to do that ?
