Microsoft is going to enable third-party app developers to start charging users monthly, via a subscription plan, for their Office and SharePoint Store apps.



From All About Microsoft:

On October 1, 2013, the Redmondians announced expansion plans for the Office Store, enabling more languages and a new subscription-pricing option available to developers building these kinds of apps.

Starting in "early spring" 2014, Microsoft will support Chinese, Russian, Dutch, Brazilian (Portuguese) and Italian language apps, officials said. Microsoft also will be adding eight new Office Store fronts -- Russia, China, Taiwan, Hong Kong, Netherlands, Belgium, Italy and Brazil.
