These drivers will be available until the official release of Windows* 8.
You must have misunderstood the question. Those drivers were provided to Microsoft for inclusion in Windows Update late last month. Those on Win8 CP should find them there. They can also be dl'd via the catalog version of WU at the link below (requires IE).
INTEL MAKES CUSTOMER HAPPY!!!!!!!!!!!
YOU REALLY SHOULD START DRIVER DEVELOPMENT BECAUSE AS SLOW AS INTEL IS IT WILL MISS THE DATE FOR THE RC IN MAY AND THE RELEASE IN OCTOBER.
I tried your link but i only get an empty page.
