The rumors were true. Keyboard app developer SwiftKey has been swooped up by Microsoft for an undisclosed fee. The company stresses its apps will "continue to be available on Android and iOS," although as we've seen with Microsoft's other acquisitions -- namely Acompli -- there's a good chance it'll eventually be rebranded or folded into another service. For instance, Microsoft's says it'll be exploring "integration of the core technology across the breadth of our product and services portfolio." That means it's interested in the underlying smarts -- the predictive word suggestions and drag-to-type interface -- as well as the app itself.
