Cubase 7 & Windows 8?

Anyone here running any of the M-Audio PCI Cards (Delta 66, 44, 1010, etc.) in Win8 (64bit) with the Win7 drivers?

M-Audio doesn’t have any W8 drivers yet and support would not tell me if they were going to release any. Obviously they have discontinued their PCI cards.

I realize that PCI is slowly dying but I have always been happy with my card and would consider the move to Win8 if I could hear a few success stories.

Anyone?
