Some of the New Service Applications and Services that have been Introduced in SharePoint 2013.

Translation Services - You can reach more people with new cloud-based translation services capable of translating not only sites, but also their content. These services have a comprehensive set of APIs, REST, and CSOM support, so content can be pretranslated when needed, or translated on the fly by users—asynchronously, synchronously, or streaming.

App Management - Applications are core to the SharePoint Server 2013 Preview experience.A SharePoint application is a secure, focused solution that is easy to develop, deploy to a marketplace, monitor, and retire.Moreover, managing applications should be easy. SharePoint Server 2013 Preview includes a new App Management Service designed to take the guesswork out of managing applications, permissions, and licensing, whether installed from the SharePoint Marketplace or Internal App Directory.

Work Management - Software should work together. With SharePoint Server 2013 Preview, you can gain a 360-degree view of workplace activities and improve communication across your organization through connected systems. A new Work Management Service provides support for action-based event aggregation across Microsoft server products, including Microsoft Exchange Server, Lync® Server, Project Server, and SharePoint Server 2013 Preview. For example, users can edit tasks from Microsoft Exchange Server on a mobile phone, and the Work Management Service aggregates tasks from Exchange Server in the My Tasks SharePoint list.

PowerPoint Automation Service  - Information is at the core of SharePoint Server, and making that information available in a variety of formats leads to broader collaboration and access to improvements in software. SharePoint Server 2013 Preview provides the new PowerPoint Automation Service (similar to the current Word Automation Service), which can automatically convert Microsoft PowerPoint® presentations into a variety of formats to promote a high degree of accessibility. Formats include converting from older Microsoft Office documents to newer Office documents, web pages, or PDFs.

Office Web Apps - Office Web Apps has evolved into a separate server product, Office Web Apps Server, that can serve multiple SharePoint farms for viewing and editing documents. In addition, a server or farm that runs Office Web Apps can be used to view files that are stored across data stores, including the following: • Microsoft server products, especially SharePoint Server, Exchange Server, and Lync Server. • File servers (URL accessible). Third parties also can integrate with the service and provide access to documents in their stores, such as EMC Documentum, IBM FileNet, OpenText, and Oracle. By separating Office Web Apps from the SharePoint farm, administrators can update servers more frequently, if desired. Administrators in large organizations can manage the scale and performance of Office Web Apps independent of the SharePoint environment. They also can serve multiple SharePoint farms, as well as Exchange Server and Lync Server, from one Office Web Apps Server environment.

User Profile Service - User profile properties drive a broad set of SharePoint features—from social collaboration to authorization. SharePoint Server 2013 Preview simplifies access to user properties with new profile import options that range from a traditional Microsoft Forefront® Identity Manager-based approach, to new direct Active Directory® Domain Services synchronization, to choices for using an external identity manager. Overall, you should see significant improvements in performance while also having greater flexibility.
