From my understanding: HP and MANY vendors will NOT release anything to support for Beta products from other vendors (third parties, in this case Windows 8). Their emplyees - specially people in their test labs - may have drivers or else but they will NOT realease for general public. You (and me) have to wait. Please bear in mind they would not support ALL PRODUCTS (depending on ages).
