Some DirectX 11.1 Features Confirmed for Windows 7
Well, as I said earlier, I’m quite sure Windows 7 will be seeing DX11.1 :)

BTW...

"Portions of the 'DirectX 11.1 Runtime' are being made available on Windows 7 Service Pack 1 via the Platform Update for Windows 7 Service Pack 1 and Windows Server 2008 R2 Service Pack 1 (KB 2670838) included with the Internet Explorer 10 Release Preview for Windows 7," he writes. "This includes the updated components above, but is limited to WDDM 1.1 drivers on Windows 7."
This means you need to have service pack 1 installed. (for those still operating without SP1 installed)
