After reporting another rough quarter on Thursday, Nokia Corp. (NYSE: NOK) is looking toward its partner Microsoft Corp. (Nasdaq: MSFT) and its upcoming Windows 8 OS to help right its ship. CEO Stephen Elop told investors it would get in right at the outset of Windows 8 and work to drive volumes in places like China, but also to take prices higher.

"The catalyst becomes the next wave of Lumia devices and the next wave after that where you will see a consistent pattern of us pushing up in price point and gross margin driven through differentiation, which we can achieve more readily now with this cycle of Windows Phone than we could with the previous cycle," Elop said on the company's earnings call.
