The latest leak in the Office 15 comes from the build 15.0.2703.1000. Windows8italia highlights some of the several updates that are included in the new images. For starters, you can see the updated Metro styling in the ribbon across the top including the new min, max, and close buttons.
The updates are subtle at this point but it's not expected that Office 15 will be a major overhaul. As Microsoft continues to move forward with the platform, new features will be built into the current platform.
The following image shows off Microsoft Limestone, this application is used to test all UI elements in alpha versions of Office. Limestone willn't ship with the final product. The platform is expected to be released during 2012 but at this point, nothing has been confirmed.
