Microsoft Office 2012 (Office 15) will probably be later this year around the same time as Windows 8 are presented. Like Office 2012 Windows 8 will be largely optimized for tablet use. The most important innovation concerned with the interface: icons and symbols in this edition of Office further apart and are slightly larger, so the more pleasant and easier to select them with your fingers. The Office ribbon, which was first introduced in Office 2007 and which you can implement changes quickly is not likely to disappear, although this is not ideal for touch usage.
The co-authoring features in Word and the Word Web App in Office 2012 improved: it is now easy to quickly see when (and by whom) the changes in a document are made. Of course the integration with other Office Web Apps and Office 365 present. Rumors also has Office 2012 on a new app (besides the existing Word, Excel, PowerPoint, OneNote, Outlook and SharePoint). This app may contribute the name Moorea offers the possibility of a Metro-like environment interface layouts with images, text and links for creating Word documents. It's wait and see if Moorea is actually in the final version of Office 2012's.
