I think it's noteworthy that Office GM Julia White talked about Microsoft being more transparent about its roadmap-- a lot of our readers criticize Microsoft for not talking enough to its customers. White was speaking specifically about Office, but her reasoning (faster iterations, cloud delivery, etc.) could just as easily be applied to other products, including Windows. It calls to mind the reports that we could see a preview of Windows 9 in April at BUILD. Then again, the talk of transparency didn't lead to any new details about Office for the iPad, or even touch-first Office for the Modern UI.
