"One of the major changes expected to be introduced with the release of Windows Phone 8, at least according to the Microsoft preview video that leaked, will be support for the platform's first dual-core processors. While Windows Phone fans take pride in how well the OS performs even on single-core chips, the rest of the industry is solidly committed to multi-core designs, and Microsoft will have to catch-up sooner or later. Just because it will be late to the dual-core party doesn't mean Microsoft won't be making a grand entrance, with a new rumor suggesting we could see phones build around the very-impressive-looking Qualcomm S4 Snapdragon MSM8960."
