Windows 8 Final isn't released yet, doubt you are going to find any drivers for it until it is.
You'll have to try to find out. Given the way it's gone for touchscreens and newer versions of Windows, my guess would be no - certainly not at full functionality.
The touchscreen works, but the buttons (to rotate screen etc...) do now. Also the graphic driver is generic and won't do the full native resolution (and looks really bad). I installed an old graphics driver but it doesn't work. Dell has had builds of Windows 8 for months now, there is no excuse for them not to have drivers out.
You will have to try Windows Vista or Windows 7 drivers. Since 8 is beta there are not going to be any WIN8 drivers available on the dell site.
There is probably a "compatability mode" for Vista/7 drivers.
Also there is an F8 bypass that you will need to to to allow unsigned drivers to be installed.
