Just a note, I was able to get the leaked Windows 8 Build 7989 installed into VirtualBox 4.0.8 (clean install from scratch took less than 30 minutes). Looks pretty good from what I've seen so far.

Unfortunately I'm not even looking at it until I update hardware, I had a hard enough time finding proper win 7 drivers for my rig. Not so much because of age but because ASUS support sucks if your gear is more than 6 months old.
